HPLC assessment of arachidonic acid release from isolated platelet membrane preparation treated with exogenous Ca2+. Platelet membrane preparation (2 mg) was treated with 1nM extraneous Ca2+ (CaCl2). The fatty acids were extracted and chromatographed in HPLC. For comparison, pure sample of arachidonic acid (Sigma) was used as standard as shown. “Sample” in the figure means isolated platelet membrane preparations after exogenous calcium incubation and “Standard” means characteristic HPLC peak for pure arachidonic acid. The sample absorbance was found to be statistically significant where P<0.01 determined by Student t-test. The results shown here is a typical representative of 7 different experiments using washed PRP from 7 different volunteers.
