Detergents protein purification
WebExtraction of the membrane proteins from the lipid bilayer is facilitated by detergents. The detergent makes the proteins partially soluble in the buffer by making a protein: detergent complex. However, the more the stringency of the detergent, higher is the probability of irreversible protein denaturation. Therefore, by rule, it is suggested ...
