Dodecyl β-D-glucopyranoside is a non-ionic detergent and surfactant commonly used to solubilize and purify membrane proteins in biochemical research. Dodecyl β-D-glucopyranoside also interacts with bovine serum albumin (BSA) to quench its intrinsic fluorescence. The critical micelle concentration (CMC) of Dodecyl β-D-glucopyranoside (DG) and DG/BSA complex is 2.0 mM and 2.34 mM, respectively. Micelles can be formed in aqueous solutions above this concentration[1].
