Supported phospholipid membrane structures on cationic organic polymer beads were prepared using mixtures of dioleoylphosphatidylserine (PS) and egg yolk phosphatidylcholine (PC). Confocal fluorescence microscopic observations using a fluorescent membrane probe (N-4-nitrobenzo-2-oxa-1,3-diazole-phosphatidylethanolamine) revealed that the phospholipid molecules in the PS/PC-bead complexes...

Flow cytometry and fluorescence-activated sorting are powerful techniques that hold great promise for studying heterogeneous populations of submicron particles such as synaptosomes, but many technical challenges arise in these experiments. To date, most flow cytometry studies of synaptosomes have relied...

The anticoagulant factor protein S (PS) protects neurons from hypoxic/ischemic injury. However, molecular mechanisms mediating PS protection in injured neurons remain unknown. Here, we show mouse recombinant PS protects dose-dependently mouse cortical neurons from excitotoxic NMDA-mediated neuritic bead formation and...
