T7 RNA polymerase
Based on 1 Customer Validation
T7 RNA polymerase is a polymerase expressed by Escherichia coli from the RNA polymerase gene of T7 bacteriophage. T7 RNA polymerase is highly specific and involved in in vitro transcription (IVT) of mRNA. In the presence of Mg2+, T7 RNA polymerase only uses the single-stranded or double-stranded DNA containing the T7 promoter sequence as a template, and uses NTP as a substrate to synthesize RNA complementary to the single-stranded DNA downstream of the promoter.

Product information
This product is recombinantly expressed in Escherichia coli .
Storage buffer: 20 mM Tris-HCl, 100 mM NaCl, 10 mM DTT, 0.1% Triton X-100, 1 mM EDTA, 50% Glycerol, pH7.9.
Reaction buffer: 400 mM Tris-HCl, 60 mM MgCl2, 10 mM DTT, 20 mM spermidine, pH 7.9
Instructions
1. Please refer to the following reaction system
0.4 μL 25mM NTP Mix, 0.2-1 ug DNA template, 2 μL reaction buffer, 0.5 μL RNase Inhibitor (optional, 1 U/μL), 1 μL 0.1 M DTT (optional), 2 μL T7 RNA polymerase, use RNase Make up the volume to 20 μL with free water.
2.Reaction conditions
Incubate at 37°C for 0.5-1h. For fragments smaller than 300 nt, it is recommended to incubate at 37°C for 2-16 h.
Notes
1. After the reaction, use 2 U DNase I (RNase-free) at 37°C for 15 minutes to remove the DNA template.
2. Adding 0.02 U thermostable inorganic pyrophosphatase to the 20 μL reaction system can significantly increase the transcription yield.

Protocolo
-
RNA extraction experimental
By lysing cells, releasing RNA, and removing impurities such as proteins and DNA, high-purity RNA products are finally obtained. The commonly used traditional method is the guanidine isothiocyanate/phenol/chloroform method (Trizol), which is suitable for a variety of animal materials including animal tissues, microorganisms, cultured cells, etc., and most plant materials.
