Description
RNase Inhibitor (Murine) is a recombinant murine source RNase inhibitor expressed in the soluble form in E. coli. It can inhibit a wide range of RNases (RNase A, B, C). It has been tested by RT-PCR, RT-qPCR and is compatible with various reverse transcriptase and DNA polymerases. Compared with human source RNase inhibitors, murine source RNase inhibitors do not contain two of the very oxidation-sensitive cysteines of human proteins, so they have higher antioxidant activity and are more suitable for experiments with high DTT sensitivity, such as qPCR.
Unit Definition
The amount of enzyme required to inhibit 50% of 5 ng RNase A activity was defined as 1 unit of activity (U). The activity of RNase A is quantitatively obtained by hydrolyzing 2 ', 3' -CMP to generate 3 '-CMP.
Quality Control
Exonuclease residue detection: 200 U of this product and 0.6 μg of λ-Hind III were incubated at 37°C for 16 h, and the DNA bands did not change after electrophoresis.
Detection of endonuclease residue: 200 U of this product and 0.6 μg of Supercoiled pBR322 DNA were incubated at 37°C for 4 h, and the DNA bands did not change after electrophoresis.
E.coli DNA residue detection: the nucleic acid residue in 200 U of this product was detected by E. coli gDNA-specific TaqMan qPCR, and the residue of E. coli genome was less than 10 copies.
Application
1. Synthesis of the first strand of cDNA
2. Polysome isolation
3. In vitro transcription
4. No cell translation system in vitro
Matters Needing Attention
1. RNase activity was inhibited by a wide range of pH values, with the maximum activity at pH 7 ~ 8.
2. Foaming or vigorous stirring (Vortex, etc.) can cause inactivation.
3. RNase H activity will not be inhibited.
