Help Please
I am using Western blot techniques to detect my proteins.  I do get bands 
for my proteins but they are too faint to be scanned.  I use the DAB-CN 
method for staining the proteins.  I've also tried chemiluminescence 
staining method, also with very little success.  Has anybody got any 
suggestions that I could try out inorder to get darker bands.
Please EMail me at:

This BIOSCI "miniFAQ" is 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/.

If you can not find an answer to your question in this or other
documentation, the BIOSCI technical support staff answers e-mail
queries sent to

		       biosci-help@net.bio.net

We can only answer questions about the use of the newsgroups and
mailing lists.  We unfortunately do not have the staff to do Internet
information searches or answer scientific questions.  Please post
those to the appropriate BIOSCI/bionet newsgroups.

0) BIOSCI NEEDS YOUR SUPPORT!!
------------------------------
BIOSCI's government funding has been expended, and we are now
operating solely from advertising revenue that we have raised from our
Web site at http://www.bio.net/.  We need just a few minutes of your
time to help us serve you.

You can do two important things which will take very little time for
you individually and will immensely help us continue to help you.

First, please use our WWW system at http://www.bio.net/ to access the
archives.  You can post or reply to messages via your Web browser as
described in item #1 below.  Your usage helps attract sponsors. If you
contact any of our sponsors, please be sure to thank them for
supporting BIOSCI. It is critical for them to get this feedback if
they are to continue their sponsorship for the long term.

Second, if you work for a company or organization that provides
products or services of interest to the biology community, please pass
this message on to your marketing or marketing communications
department or other appropriate group.  Please ask them to help
support BIOSCI by sponsoring our Web site and explain the uses and
benefits of the system to the biology community. If they are
interested, they can then contact us for further information at our
tech support address, biosci-help@net.bio.net.


1) Using the WWW to access the BIOSCI/bionet newsgroups.
--------------------------------------------------------
As of 10 December 1995, all BIOSCI/bionet full newsgroups are
accessible through the World Wide Web (WWW) at URL http://www.bio.net.
One can read and reply publicly or privately to both recent postings
and archived messages through one's Web browser if it is configured
properly to send e-mail.  Each newsgroup is equipped with its own WAIS
index.  The main BIOSCI home page also has access to the BIO-JOURNALS
Table of Contents database WAIS index and the BIOSCI user address
database described in another item further below.


2) What to do about "spams," i.e., junk mail, ads, etc.
-------------------------------------------------------
BIOSCI is a set of parallel USENET newsgroups (the "bionet" groups),
mailing lists, and a hypermail archive at URL http://www.bio.net/.
The same postings are distributed on all 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 USENET distribution from about 95% of the
spams that are being sent to date and protects the mailing lists
completely.  Moderation means, however, 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
on the USENET distribution.  Unfortunately there are easy ways for
determined spammers to override the moderation mechanism on USENET,
but we can protect our e-mail subscribers from unwanted postings if
the newsgroup is moderated.  You can also access our newsgroups over
the WWW at URL http://www.bio.net.  While this Web interface 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.  For those of you with local USENET news
systems, the Web interface will also give you faster access to new
newsgroups and recent postings.


3) 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.


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.

You might want to try extractigel columns, available from Pierce.

(As to the necessary ammonium sulphate concentration -- I have no idea.
 Many proteins precipitate at around 60% (w/w).)

The classical definition is that a type I membrane protein has its
N-terminus extracellular and its C-terminus in the cytoplasm, while
a type II membrane protein has the vice-versa orientation. Both type I
and II proteins have a single transmembrane domain. Type III proteins
have multiple transmembrane domains.

Hi Kelly,
The best classification paper for membrane proteins is (IMHO) "The
Structure and Insertion of Integral Proteins in Membranes" by S.J.
Singer (Ann.Rev.Cell.Biol. 1990, 6:247-96).
Simple schematic view of this classification you can find in TIBS 21
(May 1996) , article: "Type VI membrane proteins?" by S.Howell and
P.Crine.
Type I and II membrane proteins have one TM domain but different
orientation. Type I - N-terminus-outside,
type II - N-terminus-inside. Type III - multiple TM with different
topologies (GPCR's are III ), type IV are channels made up of multimers
of subunits and type V are attached to the membrane by covalently bound
lipids (no "classical" TM domains).

Hi all, 

I was just wondering what the criteria are for determining whether a membrane 
protein is type I or type II. I have seen that designation in a million 
papers, but upon consulting two biochem books (Stryer and Garrett & Grisham), 
a book on Protein Structure & Function, and three biochem PhDs, I was left 
un-enlightened. I'm assuming it has something to do with either the number of 
transmembrane domains, but I'm not sure.

Any help with this (even if it's a reference so I can learn instead of being 
spoonfed knowledge!!), would be greatly appreciated!

Thanks.

I have been asked to attend cell biology meeting in 12/97.  THE PROBLEM,
I have no idea of how my company's products are used in this scientific
discipline.  Are stereo microscopes used at all by molecular biologists??
 My guess is compound microscopes are used more extensively, is this a
correct assessment??  If stereo is used, what magnifications or special
lighting or options is req'd?  What % of time is spent w/ scopes?? Stereo
vs compound if applicable.  Any insights offered will be greatly
appreciated to improve my awareness.  Thx in advance to all responding
experts. Sincerrely, Mark R.:)

I *think* they use microscopes in FISH (Fluorescent in situ hybridization)
and looking at the fluorescence of cells in general.

Hope this helps some,

Looking for a postdoctoral position.

	I am writing for the possibility of doing postdoctoral research
work in one laboratory.
My research work is mainly focus on the acute desensitization of the
G-protein coupled receptors ( and particularly the phospholipase-Cb linked
receptors). I hope to get a postdoctoral position in the related research
areas (receptors, cell biology...).
Currently, I am in the process of doing my Ph.D. (thesis) in France, and I
am scheduled to finish my Ph.D. program in February of 1997.
Please feel free to contact me at    nicolas@ferre.saclay.cea.fr  if you
require any further information.(CV, references...)

Sincerely yours

I`m a doctorate student. I`m going to work with novel cervical

but there is a strong suspicion that this lines cells are contaminated
with HeLa cells. How can I probe this possible contamination? I don`t

Thought you might be interested in this warning I stumbled into on the
ATCC server.

By the way, reason number 4824 comes from the experience of a colleague
who purchased, from one of those Southern Californian mol biol stores we
get pounds of mail from every week, a human liver library that turned
out to be rat.  He attached a letter of apology for his wasted year from
the store to his grant renewal.

By the way, he got renewed.

We are letting all researchers who may have received clones from the
IMAGE/ Life Technologies mouse brain library or who
may be interested in ordering that there is significant evidence that
this library is actually from rat tissue. The following is an
excerpt of an email from John Wootton (NCBI):

"The initial discovery was made by my collaborators at NCI, Vadim
Gladyshev and Dolph Hatfield, who, incidentally deserve
credit for this and are also concerned that the community of users are
made aware of the problem. They obtained human and
mouse IMAGE clones matching a new gene and are carefully producing
finished sequence from these clones. One clone was
from the "mouse brain" library - it turned out to have 10 percent
mismatches from the other mouse clones. They searched
dbEST with their extended sequence from this clone and found it was
identical within error to ESTs from two rat libraries.

They informed me of this Tuesday July 8. I ran comprehensive searches of
the dbEST sequences attributed to this library
against the NCBI nr database using gapped blastn. In all cases examined,
where both rat and mouse orthologs exist in nr, the
ESTs from this library were identical within error to rat and
significantly (typically 7-12 percent) different from mouse. The
simplest explanation is that the entire library (4823 sequences in dbEST
as of 7/8/97) is from rat.

I did further searches to test if any other "mouse" libraries in dbEST
may be rat cDNAs, using gapped blastn searches of
dbEST with authentic rat sequences, including mitochondrial DNA. The
only libraries in dbEST that were identical within error
to these rat sequences were this "mouse brain" library and libraries
labelled rat. The Life-Tech mouse embryo libraries are
evidently authentic mouse.

The dbEST sequences from this "mouse brain" library contain a high
proportion of mitochondrial DNA matches. All of these are
almost identical to the authentic rat mitochondrial sequences in
GenBank. There are a few linked polymorphisms in some ESTs,
which suggest that that the library is a mixture of DNA from two
different strains of rat in approximate 60:40 proportion. The
authentic mouse mitochondrial sequences are approximately 15 percent
different from any of these rat sequences. This library
also contains more than half of all the rat nuclear gene matches in
dbEST: the other rat libraries are much smaller.

If you want to confirm these findings, here is a sample of GenBank rat
sequence accessions to use in blastn searches against
dbEST: M27315, J01435, V01574 (mitochondrial DNA from different
strains), M25889, J01435, M14400, J02744,
X05882, X60469, X13933, M19533, M24361, L15556 (or most other rat
housekeeping nuclear gene sequences)."
