T7 DNA Polymerase is the mesophilic, highly processive, replicative DNA polymerase from bacteriophage T7 that is responsible for the rapid and accurate replication of the virus’ genome during its infection cycle. T7 DNA Polymerase is a two subunit protein, consisting of a polymerase domain (gene 5 from the T7 bacteriophage) and a processivity factor (E. coli trxA gene thioredoxin) (1,2). The enzyme possesses a powerful (3’→5′) nuclease activity that acts on both single and double stranded DNA and appears to be responsible for the high fidelity of this enzyme and prevents strand displacement synthesis (3,4,5).Source of ProteinA recombinant E. coli strain carrying the bacteriophage T7 gene 5.Supplied in50 mM KPO40.1 mM EDTA1.0 mM DTT50% glycerolpH 7.0 @ 25°CSupplied WithB7260 (10X T7 DNA Polymerase Buffer)10X T7 DNA Polymerase Buffer (B7260)400 mM Tris-HCl200 mM MgCl2500 mM NaClpH 7.5 @ 25°CUnit Definition1 unit is defined as the amount of polymerase required to convert 10 nmol of total dNTPs into acid insoluble material in 30 minutes at 37°C.

EnzScript™(MMLV逆转录酶,RNaseH-)
摘要:基于RNA的DNA聚合酶,无核酸内切酶活性
产品描述:
EnzScript™(M-MLV逆转录酶RNaseHminus)属于RNA依赖的DNA聚合酶,该酶无RNaseH活性。EnzScript™被用于从polyAmRNA或总RNA中产生首链cDNA以用于下游的一些用途,如RT-PCR,cDNA克隆或RNA-Seq的文库构建。RNaseH结构域中的点突变能增加酶的热稳定性,相比于野生型M-MLV逆转录酶,它支持全长转录物种产生更高的cDNA产量
