A lyophilized preparation equivalent to Code: RASE. Contains some aggregates as a result of lyophilization but shows no difference in specific activity. 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 tissue-specific expression of ruminant pancreatic type ribonucleases. Ribonuclease A from bovine pancreas has also been used in a study to investigate pancreas-specific glycosylated protein disulphide-isomerase binding to misfolded proteins and peptides.
