一般描述

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.

组分

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.

单位定义

One unit will catalyze the incorporation of 1 nmol of rNTP into acid-precipitable material in 60 min at 37°C.

分析说明

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.

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

The 1918 pandemic influenza virus was the most devastating infectious agent in human history, causing fatal pneumonia and an estimated 20 to 50 million deaths worldwide. Previous studies indicated a prominent role of the hemagglutinin (HA) gene in efficient replication

Transcriptional pausing by multisubunit RNA polymerases (RNAPs) is a key mechanism for regulating gene expression in both prokaryotes and eukaryotes and is a prerequisite for transcription termination. Pausing and termination states are thought to arise through a common, elemental pause
Pemphigus vulgaris is characterized by low IgG reactivities to specific self-antigens along with high IgG reactivity to desmoglein 3.
