Foreasy HS Taq DNA Polymerase

Super HotStar Taq for PCR/qPCR

Product Description

Foreasy HS Taq DNA Polymerase is a new Taq enzyme expressed in Escherichia coli engineering bacteria by gene recombination technology . After the enzyme is treated with a special process, it's activity is inhibited before thermal activation, thereby inhibiting the non-specific amplification caused by the non-specific annealing of primers or primer dimers under low temperature conditions. This product is suitable for highly specific PCR Reaction, M ultiple x  PCR , high GC content ( > 60% ) ,with secondary structure or other strong background genomics amplification and large-scale genomics amplification detection. The enzyme has 5' → 3' DNA polymerase activity and 5' → 3' exonuclease activity, but no 3' → 5' exonuclease activity.

PCR reaction conditions vary depending on the structural conditions of templates, primers, and the like. In the specific operation, it is necessary to design the optimal reaction conditions, including annealing temperature, extension time, etc., according to the specific conditions such as the template type, the size of the target fragment, the base sequence of the amplified fragment, and the GC content and length of the primer.
