Amersham ET terminators for 3700

	I have, but never tried below 1/2 reactions. Amersham's polymerase/chemistry
allows much quicker thermal cycling (extensions are only 1min instead of 4 min).
But I think their polymerase is not as thermal stable. So while BD runs fine for
99 cycles--at least in the presence of 5% DMSO, I think the Amersham chemistry
will not.

	Also BD v3.1 under version 2.0 of data collection in our hands just gives
better results than Amersham's chemistry.

	If you are looking to save money, why not drop to 1/16th reactions with the Big
Dye--that works fine.
