Exonuclease III is a 3′→5′ exonuclease which acts by digesting one strand of a dsDNA duplex at a time or digesting the RNA strand of an RNA-DNA heteroduplex (1). Exonuclease III breaks phosphodiester bonds on the 5′ side of AP sites in both dsDNA and ssDNA (3), removes 3′ terminal groups on dsDNA (3), increases MutY turnover (4), and efficiently degrades 3′ recessed but not 3′ protruding DNA ends (creating 5′ overhangs) (5). Exo III removes a limited number of nucleotides per binding event, resulting in coordinated progressive deletions within the population of DNA molecules (1).Source of ProteinPurified from a strain of E. coli that expresses the recombinant Exonuclease III gene.Supplied in25 mM Tris-HCl50 mM KCl1.0 mM DTT0.1% mM EDTA50% GlycerolpH 8.0 @ 25°CSupplied WithB0130 (10X Yellow Buffer)10X Yellow Buffer (B0130)100 mM Bis-Tris-Propane-HCl100 mM MgCl210 mM DTTpH 7.0 @ 25°CUnit DefinitionOne unit is defined as the amount of enzyme required to produce 1 nmol of acid-soluble total nucleotide 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
