T7 RNA Polymerase, GMP Grade is derived from recombinant expression in E.coli. lt is a DNA-dependent RNA polymerase that exhibits high specificity for the promoter sequence of bacteriophage T7. T7 RNA Polymerase utilizes double-stranded DNA templates containing the T7 promoter sequence and NTPs as substrates to synthesize single-stranded RNA complementary to the downstream of the promoter. This product is manufactured and quality-controlled in compliance with GMP specifications, ensuring full traceability of the production process and raw materials. The entire production process does not involve the use of antibiotics or any animal-derived materials and excipients. Stringent controls are implemented for process-related impurities including host proteins, exogenous DNA, non-specific endonucleases, DNase, RNase, as well as microbial limits and bacterial endotoxins. This product meets the requirements for raw materials in fields such as vaccine and pharmaceutical production.
