Mastermixes for capillary PCR

Hi Lars,

we always make our own mastermix, most important is to include BSA. We
have tried LifeTec/Gibco native Taq and Roche/BM Taq in our mix: It's
the same performance. Also the same for comparison DNA hyb master or
DNA SYBR green master with our own mix. It's about the same.
You find our mixture published in:

1	N. von Ahsen, E. Schütz, V. W. Armstrong, and M. Oellerich.
Rapid detection of prothrombotic mutations of prothrombin (G20210A),
factor V (G1691A) and methylenetetrahydrofolate reductase (C677T) by
real time fluorescence PCR with the LightCycler. Clin Chem 45
(5):694-696, 1999.

There is also info about how to prepare your own mix on the idahotec
homepage (if Roche has not by now forced them to take it down). This
is the CT Wittwer mix and basically also what we are using.
