NxGen™ T7 RNA Polymerase, Biosearch Technologies
Nucleic Acid Reagents RNA Synthesis and Transcription
Lucigen’s NxGen™ T7 RNA Polymerase is superior in transcription reliability.

T7 RNA Polymerase catalyzes the 5′→3′ RNA synthesis from the T7 promoter. It is a DNA-dependent RNA polymerase cloned from the T7 bacteriophage, which recognizes the T7 promoter and terminator sequences with high specificity.

Performance Specifications: 1) Unit Concentration: 50,000 U/mL. 2) Purity (SDS-PAGE): >99%. 3) SS Exonuclease: 500 U <0.1% released. 4) DS Exonuclease: 500 U <0.1% released. 5) Endonuclease: 500 U <10% converted. 6) RNAse Contamination: 500 U = none detected. 7) E. coli 16S rDNA Contamination: 500 U <10 copies. 8) Storage: -20°C.

Source: Purified from a strain of E. coli that expresses the recombinant T7 RNA Polymerase gene.
