Abstract
Summary
Electrophoretic mobilities and thromboplastic activities of emulsions of mixtures of phospholipids derived from beef brain and egg yolk were determined. The studies included mixtures of varying amounts of phosphatidyl serine in lecithin, phosphatidyl serine in phosphatidyl ethanolamine, and phosphatidic acid in lecithin. It was concluded that the manifestation of “thromboplastic activity”by a particular phospholipid emulsion will depend largely upon the surface charge of the particles. The possibility of other factors involved was not excluded.
