Popis: We have developed a procedure for the determination of small amounts of lysophosphatidylcholine in cardiac tissue. Lysophosphatidylcholine from canine heart was separated from the major phospholipids by column chromatography, and then acetylated with labeled acetic anhydride. The acetylated lysophosphatidylcholine was isolated by thin-layer chromatography and the lysophosphatidylcholine content was calculated from the radioactivity associated with the acetylated product. Although the sensitivity of the assay depends on the specific radioactivity of the acetic anhydride used, as low as 0.5 nmol of lysophospholipid in tissue samples can be readily quantitated. The results obtained from the control and ischemic canine cardiac tissues by this assay compares favorably with those obtained by lipid-phosphorus assay. The sensitivity and specificity of the present procedure allows us and other investigators to assay for lysophosphatidylcholine content in very small (10 mg wet weight) tissue samples.
