Hotstart Taq DNA Polymerase
Kub Start Taq DNA Polymerase (Antibody modification) yog kub-pib thermostable DNA polymerase los ntawm Thermus aquaticus YT-1, uas muaj 5′→ 3′ polymerase kev ua thiab 5′ flap endonuclease kev ua.Qhov kub pib Taq DNA polymerase yog Taq DNA polymerase uas hloov kho los ntawm cov tshuaj tiv thaiv thermolabile Taq.Kev hloov kho cov tshuaj tiv thaiv tau nce qhov tshwj xeeb, rhiab heev, thiab tawm los ntawm PCR.
