Specifications and Other Information of Our T7 RNA Polymerase CAS 9014-24-8

Product Introduction

This product is the phage T7 RNA Polymerase derived from recombinant expression in E. coli. It can specifically recognize the T7 promoter sequence, and synthesize RNA complementary to downstream single-stranded DNA of the promoter using the single or double stranded DNA containing the sequence of T7 promoter as the template and NTP as the substrate.

Product Features

Excellent RNA output rate; homogeneous transcript length; transcript length up to 10K.
