title: Antibodies to platelet-activating factor (PAF) inhibit PAF-induced platelet aggregation.
abstract: Platelet-activating factor (PAF) is the most potent platelet agonist known. PAF-induced platelet aggregation was blocked by pre-incubation of PAF with the immunoglobulin fraction from sheep or rabbit anti-PAF anti-serum. Inhibition was specific for PAF and was dependent upon immunoglobulin and PAF concentrations. Antibody-mediated inhibition of PAF-activity may be a valuable method for studying the biological effects of PAF in some systems.
