Photoaffinity labeling of leukotriene binding sites in hepatocytes and hepatoma cells.
The method of direct photoaffinity labeling in the frozen state using the leukotrienes as suitable photolabile compounds may serve to identify and characterize polypeptides which interact with these eicosanoids during their hepatobiliary transport and metabolism. Furthermore, it will be a helpful technique to evaluate changes in the cell-specific protein pattern during neoplastic dedifferentiation of hepatocytes.
