TransStart® TopTaq DNA Polymerase is an engineered version of Taq DNA Polymerase combined with TransStart® technique. One binding protein binds to double-strand DNA template, preventing polymerase activity at room temperature. Other two binding proteins bind primers, preventing primer-dimer formation. Blocking proteins are released from primers and templates during the initial denaturation. This double blocking method has higher efficiency than antibody based, or chemically modified hot start PCR.
Compared with TransStart® Taq DNA Polymerase, TransStart®TopTaq DNA Polymerase has higher amplification efficiency, specificity and sensitivity. • TransStart® TopTaq DNA Polymerase offers 18-fold fidelity as compared to EasyTaq® DNA Polymerase. • The specificity is higher than antibody based or chemically modified hot start DNA polymerases. • Template-independent “A” can be generated at the 3’ end of the PCR product. PCR products can be directly cloned into pEASY®-T vectors. • Reduced nonspecific amplification and primer dimer formation. • Different from Taq antibody, no risk of contamination from mammalian DNA. • Different from chemical modification, long denaturing step is not needed. • Amplification of genomic DNA fragment up to 15 kb.
