title: [Studies on the characteristics of leukotriene B4 receptor with radio-ligand binding assay].
abstract: Leukotriene B4 (LTB4), one of the metabolites of arachidonic acid via 5-lipoxygenase (5-LO), plays important role in some inflammatory diseases as one of the most potent chemotaxis factor. A radio-ligand binding assay was set up and the characteristics of LTB4 receptor on guinea-pig splenocytes membrane were studied. At 25 degrees C, the Kd was found to be 1.55 x 10(-9) mol.L-1 and the Bmax was 2.59 x 10(-13) mol.mg-1 protein. The assay established was evaluated by nordihydroguaiaretic acid (NDGA) as positive control.
