Description

3173 DNA Polymerase is a thermostable DNA polymerase derived from a virus. Through point mutation, its 3’-5’ exonuclease activity is removed, enhancing its amplification performance. This enzyme not only has DNA-dependent polymerase activity but also RNA-dependent reverse transcriptase activity, making it suitable for single-tube RT-PCR amplification. It has strong strand displacement activity and can be used for isothermal amplification of DNA or RNA. In LAMP experiments using RNA as a template, it can achieve single-enzyme system reactions. For RNA templates with complex secondary structures, heating at 92°C for 3 seconds can yield good amplification results, whereas heating Bst pol at this temperature leads to loss of amplification activity.

This enzyme is paired with two types of buffers: 10×3173 Isothermal Buffer and 10×AM PCR Buffer. The 10×3173 DNA Polymerase Buffer is used for isothermal PCR amplification, with a reaction temperature not exceeding 70°C. The 10×AM PCR Buffer is used for conventional PCR amplification, with a pre-denaturation time at 94°C not exceeding 5 minutes.

Our 3173 DNA Polymerase is a recombinant protein expressed and purified through multiple steps.
