Taq DNA Polymerase

OverviewTechnical/SpecsLiterature/SupportOrdering Information

Versatile DNA polymerase for everyday routine PCR

Taq DNA Polymerase is a thermostable DNA polymerase that catalyzes the polymerization of nucleotides into duplex DNA in the 5' -> 3' direction. Bioneer's Taq DNA Polymerase is isolated from recombinant E.coli strain containing the DNA polymerase gene from Thermus aquaticus YT1. It exhibits its highest activity at pH 9.0 and 72°C.

Features and Benefits

Improved yield & sensitivity: Perform high yield and high sensitivity PCR using Bioneer Taq DNA polymerase.
Versatility: Use for a wide range of DNA amplifications including Real-Time PCR using TaqMan probe or SYBR Green.
Robust performance: Optimized reaction buffer enhances PCR performance.
