Effect of Sodium Ions on the Incorporation of P32-labeled Orthophosphate into Phosphatidic Acid and Inositides in Guinea Pig Brain Slices

Abstract
The effects of sodium ions and ouabain (separately or in combination) on P32-incorporation into phosphatidic acid and into inositide fractions in brain slices were investigated. Chromatographic separation of phosphatidic acid fractions on thin-layer plate and of the hydrolysis products of inositidc fractions on resin column were also made. The results were as follow;
