Data Sheet

Background: The platelet-activating factor (PAF) receptor mediates a wide range of biological responses to PAF, a potent glycerophospholipid released from a variety of cell types such as stimulated basophils, platelets, polymorphonuclear neutrophils and macrophages. PAF is involved in a diverse array of biological activities related to inflammatory and immune responses as well as cardiovascular, respiratory and nervous system physiology. In humans, various diseases have been associated with PAF, such as allergic asthma, endotoxic shock, atherosclerosis and psoriasis.

Application: Functional assays
