General description
PancreaticRibonuclease (RNase I)catalyzes cleavage of the phosphodiester bond between the 5'-ribose of anucleotide and the phosphate group attached to the 3'-ribose of an adjacent pyrimidinenucleotide forming a 2',3'-cyclic phosphate which may then be hydrolyzed to thecorresponding 3'-nucleoside phosphate. Ribonuclease A has a molecular weight of13,700 daltons. It operates in an optimum pH range of 7.0-7.5. 

The high purity Ribonuclease of Beijing GeyuantianrunBio-tech Co., Ltd.. is purified by re-crystallization, and then by Chromatography andultra-filtration.
