The product is the core raw material for nucleic acid extraction after strict screening and quality control. Polyvinylpyrrolidone, PVP, usually used as thickener, dispersant, antidote, compounding agent, lubricant and adhesive nucleic acid extraction. PVP-40 can form an insoluble complex with polyphenols, which can effectively remove polyphenols and reduce the pollution of phenols in DNA/RNA. It can also combine with polysaccharides to effectively remove polysaccharides.
