Bacteriophage T7 RNA Polymerase is a DNA-dependent RNA polymerase (99 kDa) that catalyzes in vitro RNA synthesis from a DNA sequence containing a T7 phage promoter.
The highly concentrated version T7 RNA Polymerase HC is ideally suited for set-up and optimization of high yield in vitro transcription reactions. The provided T7 IVT Set-up Buffer, MgCl2 and DTT solutions enable testing of different reaction conditions such as nucleotide/ MgCl2 concentrations.
Recommendation for assay set-up with minimal optimization: HighYield T7 RNA Synthesis Kit (#RNT-101).
Activity: 1 μl T7 RNA Polymerase HC generates >/= 30 μg RNA in 10 min at 37°. This is comparable to 1000 U of NEB’s T7 RNA Polymerase (High Concentration), #M0460T (activity assay conditions: 1x T7 IVT Set-up Buffer supplemented with 10 mM DTT, 12 mM MgCl2, 3 mM NTPs, 1 μl T7 RNA Polymerase HC and 1 μg DNA template (1.4 kpb RNA transcript) in 20 μl. RNA yield was determined with a fluorescence microplate assay.)
