产品简介

HCY™ HS-Taq DNA聚合酶是基于HCY™ Taq DNA聚合酶,经过特殊化学修饰法修饰而成。HCY™ HS-Taq DNA Polymerase具有5’-3’DNA聚合酶活性和5’-3’外切核酸酶活性,无3’-5’外切酶活性。产物3’端带A碱基,可直接用TA载体克隆。

DNA聚合酶活性只有经过98℃ 10分钟预变性后才被激活,可抑制低温条件下由引物的非特异性退火或引物二聚体引起的非特异性扩增。使用本产品进行PCR反应时可以在室温操作,并能有效避免室温操作时由于普通Taq酶或其它耐热DNA聚合酶存在活性而导致的非特异性PCR背景。

起源

本Taq DNA Polymerase为Recombinant Taq DNA Polymerase,通过大肠杆菌表达纯化获得,经过特殊化学修饰法修饰而成。

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)。

10× PCR Buffer

300 mM Tris-HCl (pH 8.8, 25°C), 500 mM KCl, 100 mM (NH4)2SO4, 1% BSA , 0.1% Triton X-100, 15mM MgCl2
