What is Interactions Between Bovine Serum Albumin and Gemini Surfactant Alkanediyl-α, ω-Bis(dimethyldodecyl-ammonium Bromide) about?
## Abstract Interactions between bovine serum albumin (BSA) and cationic gemini surfactant alkanediyl‐α,ω‐bis(dimethyldodecyl‐ammonium bromide) (12‐__n__‐12, __n__ = 3, 4, 6) in aqueous solution have been investigated by measuring fluorescence, UV‐vis transmittance, dynamic lighting scattering, and circular dichroism. Compared to a traditional surfactant dodecyltrimethylammonium bromide (DTAB), 12‐__n__‐12 interacts with BSA more strongly. With increasing concentration, 12‐__n__‐12 first binds specifically onto BSA leading to the unfolding and aggregation of BSA, and the decrease in α‐helix content; and then forms micelle‐like complexes along the unfolded BSA chains. A gemini surfactant with a longer spacer has a larger effect on BSA unfolding due to a stronger hydrophobic interaction. © 2006 Wiley Periodicals, Inc.
