Nuclease Powder is a type of enzyme preparation capable of hydrolyzing nucleic acids (DNA and RNA), with its core function being the efficient degradation of nucleic acid molecules. In molecular biology, it can remove contaminating nucleic acids from samples (such as eliminating DNA/RNA impurities during protein extraction) or be used for pretreatment in experiments like nucleic acid sequencing and gene editing to ensure experimental purity. In industrial applications, it can degrade nucleic acids in raw materials during food processing, reduce nucleic acid metabolites (such as purines), and is suitable for low-purine foods. In the fermentation industry, it can decompose microbial nucleic acids and optimize the fermentation environment. In addition, it has strong specificity (divided into DNase, RNase, etc.), enabling precise targeted degradation of target nucleic acids, and operates under mild reaction conditions. It should be noted that it needs to be stored at low temperatures to maintain activity; during use, contamination from one’s own nucleic acids should be avoided, and the corresponding type should be selected according to experimental needs.
