Mechanism of mixed liposome solubilization in the presence of sodium dodecyl sulfate
Structural transformations of vesicles to micelles that take place during the interaction of sodium dodecyl sulfate (SOS) with individual and mixed vesicles of phosphatidyl choline (PC) and phosphatidic acid (FA), have been studied by monitoring changes in optical density and in the concentration of free SOS monomer in the respective systems. Incorporation of the surfactant monomers (SOS) in th...
متن کاملGrowth of Sodium Dodecyl Sulfate Micelles with Detergent Concentration
Sodium alkyl sulfate micelles are predicted to grow as a power law of the total counterion salt concentration, Yaq, in the aqueous phase as follows: NA = K~(Y~~)Y, where N A is the micelle aggregation number and ~2 and y are constants which are estimated from the critical micelle concentration and the apparent degree of counterion attachment. For sodium dodecyl sulfate, NA = 162(Y,q)1/4 is pred...
متن کاملDetergent (sodium dodecyl sulfate) shock proteins in Escherichia coli.
The protein composition of Escherichia coli W3110 grown in the presence and absence of 5% sodium dodecyl sulfate (SDS) was examined by two-dimensional gel electrophoresis. In SDS-grown cells, at least 4 proteins were turned on, 13 were turned off, 15 were elevated, and 15 were depressed. The 19 unique and elevated SDS-induced spots constituted 7.91% of the total 35S-labeled protein. There was n...
متن کاملAnomalous solubilization behavior of dimyristoylphosphatidylcholine liposomes induced by sodium dodecyl sulfate micelles.
The solubilization dynamics of dimyristoylphosphatidylcholine (DMPC) liposomes, as induced by sodium dodecyl sulfate (SDS), were investigated; this investigation was motivated by several types of atypical behavior that were observed in the solubilization in this system. The liposomes and surfactants were mixed in a microchip, and the solubilization reaction of each liposome was observed using ...
متن کاملMechanism of interaction of sodium dodecyl sulfate with mouse interferon.
Sodium dodecyl sulfate (SDS) and other alkyl sulfates, provided they contain a minimum of 12 carbon atoms (or 322 A in length), stabilize mouse interferon (MIF) in the presence of urea, 2-mercaptoethanol, and heat. When MIF is treated with the alkyl sulfates in the absence of urea and 2-mercaptoethanol, all alkyl sulfates inactivate MIF to the same extent. This suggests that the stabilizing eff...
