UltraNuclease, also known as non-specific nuclease or broad-spectrum nuclease, is a non-specific endonuclease derived from Serratia Marcescen. It can cleave at any nucleotide within the chain, completely digesting nucleic acids into 5'-monophosphate oligonucleotides of 2-5 bases in length. UltraNuclease is capable of degrading various forms (double-stranded, single-stranded, linear, circular, native, or denatured) of DNA and RNA under a wide range of conditions (6 M Urea, 0.1 M Guanidine HCl, 0.4% Triton X-100, 0.1% SDS, 1 mM EDTA, 1 mM PMSF). It is widely used for removing nucleic acids from biological products.

This product is genetically engineered and expressed in Escherichia coli (E. coli), with a purity ≥99%. It is used to reduce the viscosity of cell supernatants and cell lysates, improve protein purification efficiency and functionality studies, and effectively prevent the clumping of human peripheral blood mononuclear cells (PBMCs) in cell therapy and vaccine research.

It is provided as a sterile liquid enzyme stored in buffer (20 mM Tris-HCl pH 8.0, 2 mM MgCl₂, 20 mM NaCl, 50% Glycerol), appearing as a clear, colorless liquid.
