产品介绍

产品描述

T7启动子是目前转录效率最高的一类启动子,因此采用T7 RNA聚合酶进行体外转录可获得更多的合成产物,T7 RNA聚合酶也是综合性能最好的RNA聚合酶,可实现大规模工业化RNA生产。

T7 RNA Polymerase(T7 RNA聚合酶) 为噬菌体 T7 DNA编码的酶,是一种高度特异识别 T7启动子序列的 DNA依赖的 5'→3' RNA聚合酶,以含有聚合酶,以含有 T7启动子序列的单链或双DNA为模板,以为模板,以 NTP为底物,合成与启动子下游的单链为底物,合成与启动子下游的单链 DNA互补的 RNA。T7 RNA聚合酶是体外转录生产治疗用 mRNA的关键酶。

本制品为利用大肠杆菌规模发酵表达的 GMP级重组 T7 RNA 聚合酶 ,采用药规格原辅料生产并严控制宿主蛋白质残留、核酸残留等,符合 GMP规范的产品生与质量管理程保障过及所有原辅料可追溯。?

Product Description

T7 promoters are currently the most efficient type of promoters. Therefore, T7 RNA polymerase can be used for in vitro transcription to obtain more synthetic products. T7 RNA polymerase is also the RNA polymerase with the best comprehensive performance, which can realize large-scale industrialization. RNA production.

T7 RNA Polymerase (T7 RNA polymerase) is an enzyme encoded by bacteriophage T7 DNA. It is a DNA-dependent 5'→3' RNA polymerase that highly specifically recognizes the T7 promoter sequence. It contains polymerase and contains T7 promoter. The single-stranded or double-stranded DNA of the sequence is used as the template, and NTP is used as the substrate to synthesize the single-stranded downstream of the promoter as the substrate, and synthesize RNA that is complementary to the single-stranded DNA downstream of the promoter. T7 RNA polymerase is a key enzyme for in vitro transcription and production of therapeutic mRNA.

This product is a GMP-grade recombinant T7 RNA polymerase expressed by E. coli large-scale fermentation. It is produced with raw materials of pharmaceutical specifications and strictly controlled host protein residues and nucleic acid residues. Product production and quality management procedures that meet GMP specifications have been guaranteed and all original The accessories are traceable.
