I have done this successfully by using a tip and scraping a
little slush off the top of my glycerol stock (0.5ml E. coli culture
0.5ml 80% glycerol) and putting about 1 microlitre in a standard reaction.
Wolfgang is right though - you should try several dilutions to see what
is best for _you_. Actually I am sometimes surprised by the gunge I can
put into a PCR at still get OK results. I am ever more surprised when
I put beautifully pure DNA into a PCR and get nothing!
