As a biological macromolecule, mRNA can be synthesized on a large scale by in vitro transcription (IVT). T7 promoter is one of the most efficient promoters at present. Therefore, T7 RNA polymerase can be used for in vitro transcription to obtain more synthetic products. T7 RNA polymerase is a T7 promoter-specific, DNA-dependent, 5'→3' RNA polymerase from T7 bacteriophage. Using double stranded DNA as the template, it transcribes RNA complementary to the single stranded DNA located at the downstream of T7 promoter. T7 RNA polymerase has been commonly used for in vitro mRNA synthesis. The polymerase is GMP Grade produced in E. coli. Our manufacturing processes are strictly controlled to ensure the end products free from host protein or nucleic acid contaminations and other impurities following the Pharmaceutical Manufacturing Guidelines. We guarantee the manufacturing and quality control comply with GMP regulation for tracking each and every step of the manufacturing process, including raw material sourcing. This product has completed the DMF record of FDA and passed the HALAL certification.
