Overview
RNase A (Ribonuclease A) is a bovine pancreatic endoribonuclease that cleaves single-stranded RNA. It catalyzes the cleavage of the phosphodiester bond between the 5’-ribose of a nucleotide and the phosphate group attached to the 3’-ribose of an adjacent pyrimidine nucleotide. This cleavage forms a 2’, 3’-cyclic phosphate, which is then hydrolysed to the corresponding 3’-nucleoside phosphate.

Overview
DNase I is a recombinant endonuclease that cleaves DNA preferentially at phosphodiester linkages adjacent to a pyrimidine nucleotide, to release di-, tri- and oligonucleotide products (on average producing tetranucleotides) with 5’-phosphorylated and 3’-hydroxylated ends.
It acts on single-stranded DNA, double-stranded DNA, RNA-DNA hybrids and chromatin. DNase I requires bivalent cations (Mg2⁺ and Ca2⁺) for maximal activity.

Overview
Proteinase K isolated from Tritirachium album is used for protease digestion during DNA and RNA preparation. It is a serine protease that exhibits broad cleavage specificity. With a molecular weight 28.900 kD, it cleaves peptide bonds adjacent to the carboxylic group of aliphatic and aromatic amino acids. It is not inactivated by chelating reagents such as EDTA or detergents such as SDS and is active over a wide range of pH (4-12.5).
