T7 RNAP

T7 RNAP.

T7 RNA polymerase active enzyme synthesizes RNA at an increasing degree of that of E. coli RNA polymerase and it terminates transcription often. T7 RNA polymerase is very selective for initiation at its own promoter sequences and is resistant to antibiotics that inhibit E. coli RNA polymerase. In-vitro transcription of mRNA is achieved via bacteriophage T7 RNA polymerase using its ability to produce full-length RNA transcripts with high reliability, thoughT7 RNAP can manufacture as well immunostimulatory by products for example dsRNA which affect protein expression.

T7 RNA polymerase Recombinant protein is produced by bacteriophage T7 DNA which is expressed in recombinant E. coli bacterial system

T7 RNA Polymerase is a DNA-dependent 5'→ 3' RNA polymerase which specifically recognizes T7 promoter sequences.
