Native Bovine Ribonuclease A


Cat No.
NATE-0655
Description
Ribonuclease A is an endoribonuclease that cleaves single stranded RNA after pyrimidine nucleotides. It attacks at the 3’ phosphate end. 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.
Abbr
RNase A, Native (Bovine)
Alias
RNase; RNase I; RNase A
Source
Bovine pancreas
Species
Bovine
Applications
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 hybridase activity of human ribonuclease-1. Ribonuclease A from bovine pancreas has also been used in a study to investigate particle-based and monolithic columns for cation exchange protein displacement chromatography.
