T3 DNA Ligase catalyzes the formation of a phosphodiester bond between a 5′ phosphate and a 3′ hydroxyl termini in duplex DNA. The enzyme will join blunt end and cohesive end termini as well as repair single stranded nicks in duplex DNA. In the absence of 20-30% PEG 6000, T3 DNA Ligase displays a very low efficiency for blunt-ended ligation. (1) T3 DNA Ligase displays a higher efficiency for joining A/T overhangs than C/G matched ends. (1) T3 DNA Ligase retains 95% of its activity in 1.0 M NaCl or KCl, with an optimal concentration of 300 mM(1).Source of ProteinA recombinant E. coli strain carrying the T3 DNA Ligase gene.Supplied in20 mM Tris-HCl300 mM NaCl1 mM DTT0.1 mM EDTA50% glycerolpH 7.5 @ 25°CSupplied With:B1010 (2X Rapid Ligation Buffer)2X Rapid Ligation Buffer (B1010):132mM Tris-HCI20 mM MgCl22 mM DTT2 mM ATP15% PEG 6000pH 7.6 @ 25°CUnit Definition1 unit is defined as the amount of T3 DNA Ligase required to ligate 50% of 100 ng DNA fragments with cohesive termini in 30 minutes at 23°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
