产品简介

HCY™ KlenTaq DNA Polymerase是嗜热型细菌Thermus aquaticus来源的热稳定性重组型Taq DNA聚合酶,经过基因改造分子量为62KD。该酶N端缺失了278个氨基酸,与野生型Taq酶相比,截断的Klentaq酶具有更高的保真性和热稳定性。该酶保留了DNA聚合酶I的DNA聚合酶活性,该酶保留了DNA聚合酶I的DNA聚合酶活性和5’→3’核酸外切酶活性,缺失3’→5’核酸外切酶活性。产物3’端带A碱基,可直接用TA载体克隆。

起源

本KlenTaq DNA Polymerase为Recombinant KlenTaq DNA Polymerase,通过大肠杆菌表达纯化获得。

活性定义

用活性化的大马哈鱼精子DNA作为模板/引物,在 74℃,30分钟内,摄入10 nmol的全核苷酸为酸性不溶物的活性定义为1个活性单位(U)。
