WebIn light of the complexity of biological membranes it is likely that nanodiscs with multiple membrane components would be more sophisticated models for membrane research. It is possible to prepare nanodiscs with more complex lipid mixtures to probe the effects of lipid composition on several aspects of membrane biochemistry. WebIn protein research, detergents are used to lyse cells (release soluble proteins), solubilize membrane proteins and lipids, control protein crystallization, prevent non-specific binding in affinity purification and immunoassay procedures, and are used as additives in …
