Product Description
General Description Binuclease is a genetically engineered endonuclease from Serratia marcescens gene that can digest all forms of DNA and RNA, including single stranded, double stranded, linear, circular and supercoiled DNA and RNA. The enzyme cleaves the phosphodiester bond of nucleic acids, producing 5 monophosphate terminated oligonucleotides 2-5 bases in length. Binuclease is not a sequence dependent nuclease, capable of cleaving the phosphodiester.
Advantages Binuclease is produced from eukaryotic yeast cells that avoid the contamination of endotoxin from prokaryotic cells. The specific activity of Binuclease was meatured at = 1000 kU/mg protein, which is much higher than any existing products (as much as 200%). Binuclease is highly stable under harsh industrial conditions and very cost effective, which make it a perfect alternative for Benzonase.
Application: Binuclease is an ideal tool to remove nucleic acids (DNA and RNA) in biological products or reduce viscosity in cell lysates. Endonuclease is widely used in the pharmaceutical industry to eliminate nucleic acid contamination in vaccine and protein products.
