the purified Tce DNA polymerase was analyzed in
the basic reaction mixture (50 ll) containing 50 mM
Tris/HCl (pH 7.5), 10 mM MgCl2, 1 mM 2-mercaptoethanol,
0.01% BSA, and end-labeled DNA substrate
at 75C for 10 min in the presence or absence
of dNTPs with 1 U Tce DNA polymerase, respectively.
The reaction was stopped by adding 1 ml 5%
(w/v) trichloroacetic acid in the presence of BSA as a
carrier. After centrifugation, the supernatant was
collected and radioactivity counted.
