WebJun 1, 2024 · SDS (sodium dodecyl sulfate) is an anionic detergent that unfolds and denatures proteins, coating proteins in negative charge. It is added in excess to the proteins, so that the proteins’ intrinsic charge is covered, and a similar charge-to-mass ratio is obtained for all proteins. In this way, the migration rate of proteins will be dependent ... WebJan 29, 2024 · The n-dodecyl-β-D-maltoside (DDM) is a glycosidic surfactant, increasingly used with hydrophobic and membrane protein isolation when the protein activity needs to be preserved. It is more efficient at protein solubilization for 2-D electrophoresis than several other detergents, including CHAPS and NP-40 .
