Product Description

T7 promoters are currently the most efficient type of promoters. Therefore, T7 RNA polymerase can be used for in vitro transcription to obtain more synthetic products. T7 RNA polymerase is also the RNA polymerase with the best comprehensive performance, which can realize large-scale industrialization. RNA production.

T7 RNA Polymerase (T7 RNA polymerase) is an enzyme encoded by bacteriophage T7 DNA. It is a DNA-dependent 5'→3' RNA polymerase that highly specifically recognizes the T7 promoter sequence. It contains polymerase and contains T7 promoter. The single-stranded or double-stranded DNA of the sequence is used as the template, and NTP is used as the substrate to synthesize the single-stranded downstream of the promoter as the substrate, and synthesize RNA that is complementary to the single-stranded DNA downstream of the promoter. T7 RNA polymerase is a key enzyme for in vitro transcription and production of therapeutic mRNA.

This product is a GMP-grade recombinant T7 RNA polymerase expressed by E. coli large-scale fermentation. It is produced with raw materials of pharmaceutical specifications and strictly controlled host protein residues and nucleic acid residues. Product production and quality management procedures that meet GMP specifications have been guaranteed and all original The accessories are traceable.

Features

It has a high degree of specificity for the T7 promoter and is used for the synthesis of RNA (including small RNA) in vitro.

Product Usage

1. Synthesize single-stranded RNA. 2. Synthesize highly specific RNA probes. 3. Synthesize siRNA precursor.

4. Make the precursor of RNA splicing reaction (RNA splicing). 5. Use cap analogs to synthesize capped RNA.

Preservation system

100 mM NaCl; 50 mM Tris-HCl (pH 7.9); 1 mM EDTA; 20 mM 2-mercaptoethanol; 0.1% Triton X-100; 50% (v/v) Glycerol.

Precautions

1. In order to effectively transcribe a specific region, it is recommended to cut the template DNA into blunt ends or 5'overhanging ends in advance in the downstream of the region.

2. Spermidine in the buffer may combine with nucleic acid to form insoluble matter. It is recommended to add template DNA at the end.
