Uvod
Proizvod je jezgrena sirovina za ekstrakciju nukleinskih kiselina nakon strogog probira i kontrole kvalitete. Natrijev dodecil sulfat (SDS) is a very efficient surfactant, which can dissolve almost all proteins. It can destroy the non-covalent bond of protein, so as to denature the protein and lose its natural conformation and function. In the application of nucleic acid extraction, SDS is often used to destroy the cell membrane (lyse cells) to release soluble substances in cells. It can destroy the connection between protein, protein lipid and lipid lipid, denature the protein structurally and destroy its three-dimensional structure. SDS will precipitate at low temperature because it belongs to the one with the highest critical micelle temperature among detergents, and this precipitation phenomenon will be more obvious in the presence of potassium salt. This characteristic of SDS can be used to remove protein from digestive juice.
