Ribonuclease A (EC cleaves RNA 3′ to pyrimidines and actively cleaves RNA at every pyrimidine residue. Ribonuclease A catalyzes the hydrolysis of single stranded RNA in the absence of metal ions or cofactors[1][2][3].

In Vitro

A major application of RNase A is the removal of RNA from plasmid DNA preparations.

Preparation of RNase A stock solution
1. Use 10 mM sodium acetate (pH 5.2) to prepare 10 mg/mL RNase A stock solution;
2. Heat at 100 ℃ for 15 min;
3. Cool to room temperature, add 1/10(v/v) of 1 M Tris-HCl(pH 7.4), adjust the pH to 7.4;
4. The solution can be stored at 20 ℃ for 2 years.
Note: When the RNase A solution is boiled under neutral conditions, RNase precipitate will form; if it is boiled at a lower pH, any precipitation may be caused by the presence of protein impurities. At this time, the precipitate can be removed by high-speed centrifugation (13 000 rpm).

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
