Analysis of AA metabolites from AA-treated platelets by thin-layer chromatography (TLC). Washed platelets from 2 to 3 mice were used for each experiment. Five microliters of [1-14C]AA (0.1 mCi/mL [3.7 MBq/mL]) was added to washed platelets and incubated at 37° C for 10 minutes. The reaction was stopped by 27 μL 1 N HCl. Prostanoids were extracted with diethyl-ether before dissolving in 50 μL chloroform for TLC analysis. Developing condition was at room temperature for 80 minutes in 30 mL chloroform-methanol–acetic acid–water ratio of 90:8:1:0.8 (vol/vol/vol/vol). Commercially obtained metabolites were included as references (marked at the left hand side). +/+ indicates WT mice; +/–, heterozygous; and –/–, homozygous mutant.
