Effect of LTB4 upon lyn, fgr, hck, and lck activity.
Cells were preincubated at 37°C for 5 minutes and stimulated with LTB4 (100 nmol/L). At the indicated times, immunoprecipitation buffer was added, and lyn, fgr, hck, and lck were immunoprecipitated, and their activity was determined by immunocomplex assay. Activity is expressed as a percentage of the control (basal counts were lyn, 30 040 ± 7105 cpm; fgr, 8462 ± 1742 cpm; hck, 20 841 ± 1161; lck, 4635 ± 852 cpm) and is the mean ± SEM of 4 to 7 independent experiments.
