The reason that I use the TaqStart antibody is that I am multiplexing at
least six different microsatellites in one tube (i.e. multiplexing the
reaction and not pooling afterwards like traditionally it has been done)
and it really helps in eliminating spurious bands.  BTW I am using
fluorescent primers and the ABI 377 to separate and size my fragments.

Multiplexing saves not only on the labor but also the amount of primer and
enzyme that you have to put in each reaction.  Since you can get away with
having a lot less of these two in each tube.

Try Multiplexing and you won't ever go back to single reaction per tube.
