Product Name

Ribonuclease A from bovine pancreas

General deion

Ribonucleases do not hydrolyze DNA, because the DNA lacks 2′-OH groups essential for the formation of cyclic intermediates. RNase can hydrolyze RNA from protein samples. Pancreatic RNase A specifically cleaves at the 3′-side of pyrimidine (uracil or cytosine) phosphate bonds.

l Biological Information

Application

Ribonuclease A is used to remove RNA from DNA plasmid preparations and protein samples. It is also used in RNA sequence analysis and protection assays. Ribonuclease A is used to remove RNA from DNA plasmid preparations and protein samples. Ribonuclease A is used for RNase protection assays, to remove unspecifically bound RNA, analysis of RNA sequences, to hydrolyze RNA contained in protein samples, and the purification of DNA. Ribonuclease A from bovine pancreas has been used in a study to assess the mechanism of heavy metal ions on RNase activity.  Ribonuclease A from bovine pancreas has also been used in a study to investigate the performance of oligomeric poly(diallyldimethylammonium chloride) as displacer for cation-exchange displacement chromatography of proteins.

Preparation Note

A further chromatographic purification of R5503 to yield essentially pure RNAse A
