The Uracil Cleavage System provides two enzymes, which, when added sequentially to a reaction containing a synthetic DNA fragment containing a deoxy-uracil, generate a single nucleotide gap at the location of the uracil residue. The system consists of two individual enzyme components, Uracil DNA Glycosylase (UDG) and Endonuclease VIII, provided at a 10X concentration to be added to a reaction containing a uracil-containing polynucleotide sequence. UDG catalyses the excision of the uracil base, creating an abasic site with an intact phosphodiester backbone (1,2). The lyase activity of Endonuclease VIII breaks the phosphodiester backbone both 3′ and 5′ to the abasic site, liberating the deoxyribose sugar (3,4).Source of ProteinEach component protein is purified separately from E. colistrains containing recombinant Endonuclease VIII and Uracil-DNA Glycosylase genes.Supplied with:UDG (G5010)10 mM Tris-HCl50 mM NaCl1 mM DTT0.1 mM EDTA50% glycerolpH 7.5 @ 25°CEndonuclease VIII (Y9080):10 mM Tris-HCl250 mM NaCl0.1 mM EDTA50% glycerolpH 8.0 @ 25°CUnit Definition, UDG1 unit is defined as the amount of enzyme that catalyzes the release of 1.8 nmol of uracil in 30 minutes from double-stranded, tritiated, uracil containing-DNA at 37°C in 1X UDG Reaction Buffer.Unit Definition, Endonuclease VlllOne unit is defined as the amount of enzyme required to cleave 1 pmol of an oligonucleotide duplex containing a single AP site in 1 hour 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
