Heat-activatable modified form of recombinant Taq DNA polymerase

NovaTaq<TMSYMBOL></TMSYMBOL> Hot Start DNA Polymerase is a chemically modified form of Taq DNA polymerase that is inactive at ambient temperature. The enzyme provides improved specificity when compared to standard Taq DNA polymerase and can minimize the generation of nonspecific amplification products, such as primer-dimers and misprimed products. The enzyme must be activated by heat treatment (710 min at 95°C), after which thermal cycling can proceed. The enzyme generates PCR products with 3′-dA overhangs, suitable for cloning with the Novagen Perfectly Blunt<TMSYMBOL></TMSYMBOL>, AccepTor<TMSYMBOL></TMSYMBOL>, and LIC Vector Kits.
