The polymorphism of bee acetylcholinesterase was studied by sucrose-gradient-sedimentation analysis and non-denaturing electrophoretic analysis of fresh extracts. Lubrol-containing extracts exhibited only one form, which sedimented at 5 S when analysed on high-salt Lubrol-containing gradients and 6 S when analysed on low-salt Lubrol-containing gradients. The 5 S/6 S form aggregated upon removal...
BACKGROUND The design, synthesis, characterization and evaluation of a novel series of non-detergent spermicides has led to the discovery of two unique molecules (DSE-36 and DSE-37) that were approximately 25 times more potent spermicides than nonoxynol-9 (N-9). METHODS Normal human spermatozoa were used to assess the spermicidal activity (Sander-Cramer Assay), the effect on sperm-membrane in...

Addition of polyoxyethylene nonionic detergents to the buffer in paper electrophoresis results in alteration of the rate of migration and shape of protein peaks. At low detergent concentrations, disruption of paper-protein binding leads to faster migration and sharper peaks. At high detergent concentrations, interaction of detergent with protein leadsto slower migration and broader peaks. On gl...
