Description

Murine RNase Inhibitor is purified from a recombinant strain of E. coli in a soluble form. It specifically inhibits the activity of RNases A, B and C through binding noncovalently in a 1:1 ratio with high affinity. This product can be compatible with Hifair™ V Reverse Transcriptase and various DNA polymerases verified by RT-PCR and RT-qPCR. Recombinant murine RNase inhibitor does not contain 2 oxidation-sensitive cysteine which are contained in human-origin RNase inhibitor. Therefore, Murine RNase inhibitor has high anti-oxidation activity and is more stable for low DTT experiments (< 1mmol/L), such as qPCR.

Compared with Murine RNase Inhibitor (40 U/µL) (Cat#10603ES), The host nucleic acid residue of UCF.ME™ Murine RNase Inhibitor (40 U/µL) is lower,which is suitable for application with more stringent requirements on background bacteria, such as pathogen detection.

Specifications

Source

Recombinant E. coli with Murine RNase Inhibitor gene

Storage Buffer

 20mM Hepes, 150 mM KCL, 8 mM DTT, 50% Glycerol, pH 7.5 @25℃

Unit Definition

The required amount of RNase Inhibitor to inhibit 50% activity of 5-ng RNase A is defined as one unit. The activity of RNase A is measured by hydrolyzing of cyclic 2', 3'-CMP to generate 3'-CMP.
