URGENT! RAPD vs. AFLP among vampire bats

Good luck with the AFLP kit.  PE's kit comes with its share of problmes.  I would
suggest designing your own primers and adaptors, and then just use your own
in-house reagents.  There are many many papers out there to use as references for
this.  Plus I would look into IRS-PCR (infrequent-restriction-site PCR).  This is a
novel technique for doing AFLP type experiments.  I have been doing AFLP, RAPD's
and IRS-PCR for about a year now and the most consistent method is IRS-PCR.
However, this is on bacteria ... not vampire bats.  But DNA is DNA.
