A monoclonal antibody against rat neutrophils, RP-1, was produced by hybridizing a mouse myeloma (P3-X63-Ag8.653) with BALB/c mouse spleen cells sensitized with peritoneal neutrophils from Wistar-King-Aptakeman/Hok rats. RP-1 specifically reacted to neutrophils and bone marrow cells from rats of various strains. The expression of an antigen reactive to RP-1 on rat peritoneal neutrophils was enhanced by stimulation with phorbol myristate acetate and concanavalin A. The experimental result that the expression of an antigen reactive with another anti-neutrophil monoclonal antibody was not enhanced by stimulation with phorbol myristate acetate indicates that the antibody-binding capacity of stimulate neutrophils was not nonspecifically enhanced. The enhancement of antigen expression was temperature dependent. A glycolytic inhibitor, 2-deoxy-D-glucose, and an inhibitor of intracellular calcium mobilization, 3,4,5-trimethoxybenzoic acid 8-(diethylamino)-octyl ester hydrochloride, which inhibited hydrogen peroxide release from stimulated neutrophils, did not inhibit enhancement of the expression of an antigen reactive with RP-1.
