ok...here we go....have any of you who have used rapd primers and done a no 
template control (to check for contamination) get what i do?
for almost all primers i've used i get STUNNING amplification products ranging 
from 200bp up to 2.5kb with single RAPD primer and no dna at all....consulting 
the refs......this is 'normal'...however it is a little offputting that the 
control rxns produce so many artifactual bands.....anyone out there shed some 
light as to how a single 10mer primer can cause so much secondary structures 
so as to create these large products?.........thanks for any advice

After working with RAPDs and mites (which have so little DNA I cannot quantify)
I have finally found a few interesting items.
     1. I have now three protocols that work for bees, blood and mites, if 
anyone is interested, contact me.
     2. I have found that spurious banding patterns will go away if the 
annealing temperatures are raised from 37 to 40 or higher.
     3. I am still having trouble extracting DNA from these mites.  Can anyone 
give me suggestions? I have tried the Phenol/chloroform, salt, and KoAC for 
Drosophila. All work except the former.  Bee DNA cleans up  nicely with 
dialysis but I loose too much mite DNA.

Thanks in adavance

Your results do not seem 'normal' to me.   We run two 'no template' 
reactions on each gel and almost never get bands in those lanes.  If we 
do get bands in the control lanes we conclude that we have somehow 
contaminated our reaction mixture and toss the whole gel out and redo the 
reactions.  I have been told that a low molecular weight band (<200 bp) 
we get with some primers (the band appears on every lane regardless of 
the template source) is due to the polyprimer association you speak of, 
but there is never more than one band even in blank lanes.

I used to get these too, but in  the last year I have pretty much 
eliminated them.  I don't know how, but I use University of British 
Columbia RAPD primers, P-E Amplitaq, P-E buffer II, P-E MgCl2, and 
ProMega dNTP's.  The DNA is prepared using buffers I mix myself using 
HPLC-grade water.  I use Boehringer-Mannheim Proteinase K.  

I have recently tried the P-E Stoffel fragment and I get terrible 
results with my DNA (crude extract of Drosophila pseudoobscura).  
Also, the Stoffel fragment DOES give me lots of bands in a tube with no 
template.  Other people here use Stoffel fragment with good results, 
although they tell me that it seems to preferentially amplify smaller 
fragments.  I am going to stick with Amplitaq for my current project.

Also check out Genosys. They have quite a few arbitrary 10-mer kits
available. In addition, a new product has recently become available
called the decamerarray. It is a library of 1,040 10-mers with G+C
contents ranging from 50 to 80 percent.

Please do not send responses to commercial messages back to rapd.  If 
you would like to vent your frustrations, may I suggest that you do 
what I do?  Forward the complete message, with your comments, to the 
postmaster of the offending person.  For instance, if the commercial 
message came from SOMEPERSON@GREEDY.COM, forward the message back to 
POSTMASTER@GREEDY.COM.  If a postmaster gets enough complaints, 
that person may take steps against the offending party.  At least, it 
gives me a little satisfaction to try.

Hi there,

I will get those bands you describe, depending on the RAPD primer. I have
cleared almost all of the "no template" bands by using the Taqstart
antibody from Clontech. I have no ties to Clontech.


Good Luck,

I agree...

It is not 'normal' to get contaminations in the amplification controls !!!
We use RAPD only to check the 'PCR quality' of DNA to be amplified
for the detection by PCR of bacterial pathogens but our negative control
(i.e. without added DNA) should  be always(and are) without contaminating
 bands...

Dear netters,
Please be patient with me, I know this is not strictly a RAPD problem 
but I have tried other means without much success.
I would like to know if anyone out there has the E-mail addresses of 
the following scientists:-

Chris Lamb, the Salk Institute, La Jolla, CA

Andrew Staehelin or Felix Mauch, University of Colorado, Boulder.

John A. Ryals, CIBA-GEIGY Corporation, North Carolina.

I hope there will not will be not too many complaints about misuse of 
the network, at a time when there is obviously a large number of 
people abusing the system.

Thankyou in advance for any help that you can give,

yours sincerely 

David

This is a new "miniFAQ" designed to answer the questions that come up
the *most frequently*.  The main BIOSCI FAQ (Frequently Asked
Questions) is accessible on the World Wide Web at URL
http://www.bio.net/.

	Contents:
	--------
	1) What to do about "spams," i.e., junk mail, ads, etc.

	2) Examples of subscribing and unsubscribing to the mailing lists.

	3) How to access BIOSCI/bionet newsgroup archives.

	4) The BIOSCI user address and research interest directory.


1) What to do about "spams," i.e., junk mail, ads, etc.
-------------------------------------------------------
BIOSCI is a set of parallel USENET newsgroups (the "bionet" groups)
and mailing lists.  The same postings are distributed on both media
(except for a small number of mailing-list-only groups at
net.bio.net).  Unfortunately it is becoming a despicable practice on
the Internet (by a few people out to make a fast buck) to do automated
mass postings to thousands of newsgroups and mailing lists.  These
attempts to grab free advertising are refered to as "spams" in the
usual, somewhat boneheaded, net terminology.  USENET is more
susceptible to this practice, and many spams originate on the USENET
groups and then are passed on to the mailing lists.  However, spammers
also get lists of mailing addresses and hit these too, so neither
medium is immune.

What should you do personally if you get junk mail?
---------------------------------------------------
Just delete it and move on without reading it further.  Filing a
protest is becoming increasingly useless because spammers are often
disguising the addresses where the messages are sent from.  Unless you
really understand Internet mail systems, your attempt at protest by
sending replies to the message will often end up being sent to the
address of an innocent person that the spammer is victimizing.

What can BIOSCI/bionet do to protect its newsgroups?
----------------------------------------------------
The only solution currently available is to moderate the newsgroup.
If this newsgroup is already moderated, then you are in good shape.
Moderation protects the newsgroups from about 95% of the spams that
are being sent to date.  This means that someone has to take the time
to review each message before it goes out.  We have set up software
here that simply allows the moderator to forward to an address at
net.bio.net messages that (s)he wishes to have distributed.  This
takes no more time than that needed to read the message and pass it
on, say about 1 min. per message.

Most newsgroups currently have a discussion leader who is responsible
for their newsgroup.  The discussions leaders and their e-mail
addresses are listed in the BIOSCI Information Sheet which is
available on the Web at http://www.bio.net/.  If a newsgroup is being
hit with too many junk postings, please contact the discussion leader
for that group and see if there is interest in moderating the group.
Please do not assume that by simply posting a complaint to the
newsgroup itself, anyone on the BIOSCI staff will act on your
complaint.  With close to 100 newsgroups to run, the BIOSCI staff has
to rely on the discussion leaders of each newsgroup to report problems
directly to us at biosci-help@net.bio.net.

We will moderate any of our newsgroups if the discussion leader tells
us that the readership of the group wishes to do so and if a moderator
is willing to do the work.  For most BIOSCI/bionet groups, this
entails only a few minutes of work each day.

Moderating a newsgroup will resolve probably 95% of the junk postings.
Unfortunately there are easy ways for determined spammers to override
the moderation mechanism.  We are working on new systems to provide
access to our newsgroups over the WWW.  These should be available
soon, probably November 1995, and will allow you to use your Web
browser to look at the news postings.  While this will not stop
spammers from trying to post to the groups, this will give you yet
another way, besides using USENET news, to keep the junk out of your
personal mail files.


2) Examples of subscribing and unsubscribing to the mailing lists.
------------------------------------------------------------------
PLEASE NOTE: The BIOSCI management does NOT act on
subscription/unsubscription requests that are posted improperly to the
newsgroups and mailing lists.  People who do this only bother everyone
on the lists to no avail.  Please be sure to follow the proper
procedures below.

Gory details are in the BIOSCI Information sheets on the Web at
http://www.bio.net.  Below we give an example utilizing the
METHODS-AND-REAGENTS list at both of our two BIOSCI sites:

Users in the Americas and Pacific Rim countries who use the BIOSCI
------------------------------------------------------------------
node at computer net.bio.net:
----------------------------

A) Determine the "listname" which is the <=8 character mail address
                                         ^^^^^^^^^^^^^
   for the group.  These can be found in the BIOSCI Info. Sheet.  For
   the METHODS-AND-REAGENTS group the mailing address is
   methods@net.bio.net.  The listname is the portion of the address to
   the left of the @ sign, i.e., "methods".  The listname is used with
   the "subscribe" and "unsubscribe" commands illustrated below.

B) Mail all commands in the body of a mail message addressed to
   biosci-server@net.bio.net.  Do NOT send commands to the newsgroup
   posting addresses!  Leave the Subject: line blank, any text on it
   will be ignored.

C) In the body of your message put one or more of the following
   commands with an "end" command on the last line, e.g.,

   subscribe methods
   unsubscribe methods
   end

   Do NOT put your e-mail address or other text on these lines.  The
   server only allows you to cancel your subscription if the address
   on your mail header matches the address on our mailing list.
   Please ask for help at biosci-help@net.bio.net if your address has
   changed, e.g., if you know you are on the list but the server tells
   you that you are not a member.


Users in Europe, Africa, and Central Asia who use the BIOSCI node at
--------------------------------------------------------------------
computer daresbury.ac.uk (also known as dl.ac.uk):
-------------------------------------------------

To subscribe and unsubscribe to/from the BIOSCI lists, you need to
specify the full USENET newsgroup name with "bionet-news." prepended.
The USENET newsgroup names are listed in the BIOSCI Information sheet
on the Web at http://www.bio.net/.  For the METHODS-AND-REAGENTS list
the USENET newsgroup name is bionet.molbio.methds-reagnts, thus the
appropriate commands are

    sub bionet-news.bionet.molbio.methds-reagnts

    unsub bionet-news.bionet.molbio.methds-reagnts

These commands are included in a message addressed to mxt@dl.ac.uk,
NOT to the newsgroup mailing addresses.  As usual, include the text in
the body of the message as text on the Subject: line is ignored.

To unsubscribe from all the lists at the UK node, use

    unsub bionet-news

Please note that if the address in the list is different than the one
in your mail message header, you will not be able to unsubscribe by
this method. If you have problems, please mail biosci@daresbury.ac.uk.


3) How to access BIOSCI/bionet newsgroup archives.
--------------------------------------------------
Back postings of all BIOSCI/bionet newsgroups can be found on the
World Wide Web at URL http://www.bio.net/.  There are several
searchable newsgroup indices at this site.  E-mail users can search
the BIOSCI archives by using our waismail e-mail server.  For
instructions send the message

help

to waismail@net.bio.net.  Leave the Subject: line blank (anything
entered on the Subject: line is ignored).


4) The BIOSCI user address and research interest directory.
-----------------------------------------------------------
Please take this opportunity to add your name, address, and research
interest information to the BIOSCI User Address Database if you have
not already done so.

You can fill out the address form directly through our Web page at URL
http://www.bio.net/adrform.html.

The address database is reindexed nightly for WWW access (the URL is
http://www.bio.net/).  If you are not directly on the Internet but can
reach it by e-mail, please use our waismail server to access the user
directory.  waismail use is described above.  You can also request a
user address form by e-mail from biosci-help@net.bio.net.

Please check your database entry from time-to-time to see if your
address information is still up-to-date.  Because of our limited
personnel resources, we ask that you resubmit a *complete* form to
revise your entry; we only replace complete entries and do not have
resources to edit old forms.

Hi Netters!

I am contemplating a purchase of Gel Documentation and Analysis
system for use in the RAPD analysis programme that we have here. I
would appreciate your views and experiences regarding these
systems. If you have any, please mail back to me on my personal
address.

To start with I have shortlisted the following :

1. Stratagene make Eagle Eye II still video system priced at around
   DM 40000, including software and Customized computer
2. Biorad make Gel Doc 1000 Fluorescent Gel System priced at around
   $21000, including software but does not include a Computer.
3. UVP Gel Documentation system priced at Pound Sterling 8000
   without computer and software.

I prefer IBM-PC and compatible hardwares running on DOS 6.22 or
higher and/or Windows. What, if any, specific requirements have to
be satisfied by such systems especially with reference to the CCD
Camera and Frame-Grabber cards? Has anyone used more than 1 type of
system and if so which of them was the better one? Can data
generated by the system be read by a RAPD or RFLP analysis software
which in turn can permit several statistical analyses such as
distance estimates, cluster analyses etc.?

Thanking you all in advance,

Sincerely,

Shirish Ranade

please be sent directly to me at the addresses given below, and not

Nadia, et. el.:

We have observed non-primer dimer bands in no-template DNA controls with 
certain of our UBC primers too.  Many primers do not give artifactual 
bands, however.  The problem lies with DNA contamination in the DNA 
polymerase of bacterial origin.  The amount of contaminating DNA will 
vary between suppliers and lots, but will always be present to a certain 
extent.  Of course contaminating DNA in trace amounts is impossible to 
avoid in the Taq purification process (regardless of supplier's claims), and 
contaminating DNA is easier to amplify and thus detect by the RAPD 
process than by standard PCR.  The observation that only certain primers 
will amplify the contaminating bacterial DNA, presumably derives from 
sequence homology.  No amount of purification of the primers or buffers 
will help in this case.  On the other hand, when you use about a 
nanogram of template DNA, the small amount of contaminating DNA in 
the Taq will be swamped by your template and will not compete effectively 
for primer and thus should not affect your results.  It never 
affects our results when we use commercially available Taq anyways (i.e.
we do not see the two or three bands in the control lane in our amplified 
experimental samples).  Cheers.

Well I am releaved that people using RAPD primers are getting
bands in there negative (water) controls, I thought I was the only
one. I to get wonderful bands in the negative controls that range from
about 200 base pairs - to as high as 1800 base pairs. I also must add to
say, that I got negative controls with some primers that had one bands
as high as 1000 base pairs, and other primers that provided me with a
multitude of bands. I am using primers from UBC, and I have tried a
number of various ways to account for the possible presence of the
bands: I changed the water of my negative control, fearing that
it may have been contaminated, I have changed the diltutions of the
DNA thinking that it may have been the DNA that was contaminated, but
I still had presence of these bands. I eventually used the Mermaid Kit
from BIO101, it consists of a silica base, that should help in the
purification of primer of at least 10 nucleotide base pair long. This
provided me with some success; however, the cleaning is not always that
effective, and sometimes the negative controls still showed presence
of bands.

So I do not believe that absence of bands in the negative control
could not be present.

This  is   the  reply   for  the  artifactual   bands  problems  using   RAPD  primers 
(XKA52@musicb.mcgill. ca: rapd artifactual bands).  

We  have  used UBC  primers  in  watermelon, barley,  wheat  genome,  etc. and  my 
manuscript of  "Detection of genetic diversity  using RAPD-PCR and  sugar analysis in 
watermelon"  was recently  accepted  by TAG  journal.   We  are always  using  UBC 
ten-mers to eliminate external contamination as follows;

1) purchase the commercial Taq  polymerase which was the least contaminated bacterial  
   DNA
2) add only the least amount of Taq polymerase required
3) use DEPC-treated  water in all the reaction solution,  even to dissolve and dilute the    
   primers
4) work this experiment on clean-bench all the times
5) use the tips and tubes autoclaved
6) reduce the magnesium contents as possible

As J. Carlson answered previously, I think  that the enzyme is the main source of DNA 
contamination during  the manufacturer's purification process.   In our  lab, we had  not 
any artifactual  bands shown except DNA-primer  dimers using UBC primers  (it would 
be the  same if we use  other 10-mers).  However,  you probably could try  to use the 
decontamination method using ultra-violet inactivation as  the papers of Nature Vol. 343, 
p27;  Vol. 345,  p773; Vol  347, p340,  but we  found these  process  would be  useless.  
Therefore, please  think about your  enzyme and  its concentration you  have used, and 
DEPC-treated water at first.
Thanks.

This thread pops up periodically, and I thought it was pretty much accepted that
the common phenomenon of bands in RAPD negative controls is due to contaminating
Thermus aquaticus DNA in the enzyme preparation.  Using specific primers, this 
DNA wouldn't be a problem (unless you have "univeral" bacterial primers), but it
makes itself evident with non-specific RAPD primers.  It is also my impression 
that people don't worry about these bands too much (and in my experience they 
aren't much of a problem).  They are faint and inconsistent, and do not 
interfere (in my experience) with reproducibility of RAPDs on your actual 
template.  As long as your sample results are reproducible, and none of your 
sample bands correspond to the bands in the negative control, then you ought to 
be able to proceed without undue concern.

Well I am releaved that people using RAPD primers are getting 
bands in there negative (water) controls, I thought I was the only
one. I to get wonderful bands in the negative controls that range from 
about 200 base pairs - to as high as 1800 base pairs. I also must add to 
say, that I got negative controls with some primers that had one bands 
as high as 1000 base pairs, and other primers that provided me with a 
multitude of bands. I am using primers from UBC, and I have tried a 
number of various ways to account for the possible presence of the 
bands: I changed the water of my negative control, fearing that
it may have been contaminated, I have changed the diltutions of the 
DNA thinking that it may have been the DNA that was contaminated, but 
I still had presence of these bands. I eventually used the Mermaid Kit 
from BIO101, it consists of a silica base, that should help in the 
purification of primer of at least 10 nucleotide base pair long. This
provided me with some success; however, the cleaning is not always that 
effective, and sometimes the negative controls still showed presence
of bands.
     
So I do not believe that absence of bands in the negative control 
could not be present.

Does anyone know of work done on parasitic hymenopterans using rapds or
microsatellites for identification of biotypes?  I'm especially interested
in braconids.  I'm also interested in any work done using these methods on
other insects.
