MaxNuclease, a broad-spectrum nuclease, is derived from Serratia Marcescen. It is expressed by genetically engineered E.coli and purified, all in a GMP-Grade environment. This enzyme can degrade all forms of DNA and RNA, including single-stranded, double-stranded, linear, circular, native, and denatured nucleic acids. It digests them into 5'-monophosphate oligonucleotides of 3-5 bases in length, and has no base recognition specificity. MaxNuclease can maintain high stability and enzyme activity under a wide range of conditions and is suitable for removing nucleic acid residues in samples and improving product purity in pharmaceutical industries such as viral vaccines, viral vectors, and recombinant proteins.
