T4 Polynucleotide Kinase (PNK) catalyzes the transfer and exchange of the terminal gamma position phosphate of ATP to the 5′-hydroxyl terminus of double-and single-stranded DNA, RNA and nucleoside 3′-monophosphate molecules (1). T4 PNK also exhibits 3′-phosphatase and 2′, 3′ cyclicphosphodiesterase activities (2, 3, 4, 5, 6).Source of ProteinPurified from a strain of E.coli that expresses the recombinant T4 Polynucleotide Kinase gene.Supplied in10 mM Tris-HCl50 mM KCl0.1 µM ATP1.0 mM DTT0.1 mM EDTA50% glycerolpH 7.4 @ 25°CSupplied WithB9040 (10X T4 Polynucleotide Kinase Buffer)10X Polynucleotide Kinase Buffer (B9040)700 mM Tris-HCl100 mM MgCl250 mM DTTpH 7.6 @ 25°CUnit DefinitionOne unit is defined as the amount of enzyme catalyzing the incorporation of 1 nmol of [32P] (ATP donor) in 30 minutes at 37°C in 1X T4 Polynucleotide Kinase Reaction Buffer.

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
