Gene Information
bacteriophage T7 ... T7p07(1261050)
General description
T7 RNA polymerase is highly specific for the bacteriophage T7 promoter and terminator sequences. It is extensively used to prepare RNA transcripts for stuctural and metabolic studies. The RNA transcripts can be converted to probes for sensitive hybridization detection studies. T7 polymerase and dideoxynucleotides can be used to directly sequence DNA.
Analysis Note
Activity assay: 40 mM Tris-HCl, pH 7.9, 6 mM MgCl2, 4 mM spermidine, 10 mM DTT, 0.5 μM each rNTP + 10 μCi α-32P-UTP, 3-10 units of enzyme, and 1 μg of a 350 bp template are incubated for 10 min at 37°C in a total volume of 100 μl. Typical results are ≥50% incorporation of labeled nucleotide into ≥90% full-length transcript.
Other Notes
One unit will catalyze the incorporation of 1 nmol of rNTP into acid-precipitable material in 60 min at 37°C.
T7 RNA Polymerase is supplied as a solution of 100 mM NaCl, 50 mM Tris-HCl (pH 7.9), 0.1 mM EDTA, 0.1% Triton X-100, 1 mM DTT, and 50% (v/v) glycerol.

RNA synthesis by T7 RNA polymerase or SP6 RNA polymerase is 100-1000 times more sensitive to the presence of the 3'-deoxyribonucleoside 5'-triphosphate chain terminators than is RNA synthesis by Escherichia coli RNA polymerase or Q beta replicase. These ribonucleotide analogues
