Plasma membrane isolation and fatty acid analysis of membrane lipids from murine lymphocytes

Plasma membranes have been isolated in high yield by a novel method from splenic lymphocytes of BALB/c mice. These membranes were purified in predominantly envelope form, essentially right-side out, by zinc stabilization and sucrose density gradient centrifugation. A simple, rapid method was used for derivatization and analysis of fatty acids in plasma membrane lipids.
