Critical Micelle Concentrations of Gangliosidest
The micellar properties of mixed, bovine gangliosides and purified galactosyl-N-acetylgalactosaminyl(Nacetylneuramin yl)galactosylglucosylceramide were studied by gel filtration, equilibrium dialysis, and band and boundary centrifugation in sucrose gradients. The dissociation of micelles is very slow (days) in water and required us to approach equilibrium by association of monomers rather than ...
متن کاملQSPR Study for Predicting Critical Micelle Concentrations of Gemini Surfactants
CMC (critical micelle concentration) is lowest concentration when micelle was created in aqueous solution of surfactant. In this study, we collected CMC data to develop the QSPR model of gemini surfactants from literatures. Gemini surfactants are composed of two monomeric surfactant molecules linked by a spacer chain. Gemini surfactants can self-assemble at concentrations almost a hundred-fold ...
متن کاملBiological effects of lipoteichoic acids.
Pneumococcal lipoteichoic acid (Forssman antigen) added to the medium of growing pneumococcal cultures caused chain formation, prevented culture lysis in the stationary phase of growth, and inhibited lysis by penicillin and by the pneumococcal bacteriophage Dp-1.
متن کاملLipoteichoic acids from Streptococcus sanguis.
Two lipoteichoic acids, membrane (MLTA) and wall (WLTA), have been purified from Streptococcus sanguis by Sepharose and Ecteola-cellulose column chromatographies and concanavalin A-conjugated Sepharose affinity column chromatography. The teichoic acids were homogenous as judged by disc gel electrophoresis, column chromatography, and double diffusion tests. Both MLTA and WLTA consisted of glycer...
متن کاملStructure/function relationships of lipoteichoic acids.
The role of lipoteichoic acids (LTAs) from Gram-positive bacteria as immunostimulatory molecules was controversial for many years, as inadequate preparation methods as well as heterogeneous and endotoxin-contaminated commercial preparations led to conflicting results. An improved purification methodology for LTA now yields potent bioactive and chemically defined material, which is currently bei...
