T7 RNA Polymerase is a DNA-dependent RNA polymerase that exhibits extremely high specificity for its cognate promoter sequences. Only T7 DNA or DNA cloned downstream from a T7 promoter can serve as a template for T7 RNA Polymerase-directed RNA synthesis.
Features - Benefits
Specific: T7 RNA Polymerase exhibits extremely high affinity and specificity for T7 promoter sequences.
Highly Pure: T7 RNA Polymerase is judged to be greater than 90% pure as determined by SDS polyacrylamide gel electrophoresis. Free of detectable levels of contaminating RNase and DNase activity (<1% release).
Flexible: Will incorporate 32P, 33P, 3H and 35S nucleoside triphosphates.
Provided with 5X Reaction Buffer: Provided with 100mM DTT and Transcription Optimized 5X Buffer: 200mM Tris-HCl (pH 7.9 at 25°C), 30mM MgCl2, 10mM spermidine, 50mM NaCl.
