商品信息

HoTaq? DNA Polymerase is a hot-start
Taq
DNA Polymerase, which is chemically modified form
Taq
DNA Polymerase.




Description:
HoTaq? DNA Polymerase is a hot-start
Taq
DNA Polymerase, which is a chemically?modified form of
Taq
DNA Polymerase. HoTaq DNA Polymerase is provided in an inactive state and has a minimum enzymatic activity at ambient temperatures. It will become active after 10 minutes heating at 95?C. This prevents the formation of misprimed products during reaction setup and the first denaturation step, leads to high PCR specificity. It is suitable for diagnostic reaction without the miner band. The enzyme is a high processive 5'-> 3' DNA polymerase that lacks 3'-> 5' exonuclease activity. Each lot of HoTaq DNA polymerase is tested for PCR amplification.

Source:
An
E. coli
strain that carries the
Taq
DNA Polymerase gene from
Thermus aquaticus
(same as
Taq
DNA Polymerase).
