                 DNA Polymerase for Hot Start PCR
SurePRIME™ DNA Polymerase is a highly purified form of recombinant Taq DNA Polymerase
that has been chemically modified by the addition of heat-labile blocking groups to specific
amino acid residues. Prior to PCR, in its inactive state, SurePRIME™ DNA Polymerase is inca-
pable of extending primer-dimers or mis-annealed primer-template species that form below the
specific annealing temperature. The 95°C incubation step therefore serves to activate the
enzyme and also to ensure a completely "clean" initial PCR cycle.

Polymerase was performed under challenging PCR conditions. A 400 bp region of the human
ß-globin gene was amplified using specially designed non-optimized primers. The primer set
contained mismatched bases at the 5' end to introduce restriction sites.
