一般說明
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.
成分
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.
單位定義
One unit will catalyze the incorporation of 1 nmol of rNTP into acid-precipitable material in 60 min at 37°C.
分析報告
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.

DNA-dependent RNA polymerase (RNAP) synthesizes RNA complementary to the template DNA. During transcript elongation, RNAP often undergoes backward translocation ('backtracking') by dissociating the 3' end of the nascent RNA transcript from the template DNA. While the backtracked state of RNAP
