Proizvod je jezgrena sirovina za ekstrakciju nukleinskih kiselina nakon strogog probira i kontrole kvalitete. 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.
