产品介绍

本品是以可溶形式在大肠杆菌中表达纯化的重组RNase抑制剂,分子量约65 KDa 的广谱型RNase抑制剂。RNasin能够特异地与RNase以非共价键结合形成复合体从而 使RNase失活,而不抑制RNase H、S1核酸酶、SP6、T7或T3 RNA 聚合酶、AMV或 M-MLV反转录酶、Taq DNA聚合酶、RNaseT1等酶的活性,不影响后续的反转录及翻 译过程。广泛的应用于RNA方面的研究,如RT-PCR,cDNA合成,mRNA的保护,体 外转录和体外翻译,制备RNase-Free的抗体,原位杂交和mRNA定位等。

This product is a recombinant RNase inhibitor expressed and purified in soluble form in Escherichia coli, with a molecular weight of approximately 65 KDa and a broad-spectrum RNase inhibitor. RNasin can specifically bind to RNase in a non covalent bond to form a complex, thereby inactivating RNase, without inhibiting the activity of RNase H, S1 nuclease, SP6, T7 or T3 RNA polymerase, AMV or M-MLV reverse transcriptase, Taq DNA polymerase, RNaseT1 and other enzymes, without affecting subsequent reverse transcription and translation processes. Widely used in RNA research, such as RT-PCR, cDNA synthesis, mRNA protection, in vitro transcription and translation, preparation of RNase Free antibodies, in situ hybridization, and mRNA localization.
