Description
Our Ribonuclease A Solution is a non-specific ribonuclease derived from bovine pancreas that has been modified through protein engineering technology. It is obtained through yeast expression and purification. It does not contain bacterial endotoxins expressed by prokaryotes. Functionally, RNase A is a ribonuclease that can hydrolyze the phosphodiester bond between the 5 '- ribose on a nucleoside and the phosphate group on the adjacent pyrimidine nucleoside 3' - ribose. The resulting 2 ', 3' - cyclic phosphate can be hydrolyzed into the corresponding 3 '- nucleoside phosphate. Therefore, single stranded RNA can be specifically degraded at the positions of C and U nucleotide residues. RNase A is very stable. RNase A exhibits high efficacy when acting on single stranded RNA.
This product is widely used to remove RNA contamination from DNA or protein samples.
This product is free from contamination by endonucleases and exonucleases, as well as protease contamination.
