Description
Ribonuclease A (RNase A) is a non-specific endoribonuclease derived from bovine pancreas, engineered using protein engineering technology and produced via yeast expression and purification. It is free of bacterial endotoxins commonly associated with prokaryotic expression systems.
Functionally, RNase A is an endoribonuclease that hydrolyzes the phosphodiester bond between the 5′-ribose of a nucleotide and the 3′-ribose phosphate of an adjacent pyrimidine nucleotide (cytidine or uridine). This reaction generates a 2′,3′-cyclic phosphate intermediate, which is subsequently hydrolyzed to the corresponding 3′-nucleotide phosphate. Thus, RNase A specifically cleaves single-stranded RNA after C and U residues. RNase A is highly stable and exhibits strong activity against single-stranded RNA.
This product is widely used to remove RNA contamination from DNA or protein samples.
It is free of endonucleases, exonucleases, and proteases.
