For the past couple of months we have been running PCR products from our
plant microsatellites (100-300 bp) on small non-denaturing acrylamide gels
and staining with EtBr.  Works quite well, but I'm not sure if we can
reliably detect 2bp differences.  The ultimate detection method is to use
fluoresently labelled primers and run on an ABI 373 with the GeneScan
Software - gives single bp sizing and automatic alelle calling.
