Antibody to platelet activating factor (1-O-alkyl-2-acetyl-sn-glycero-3-phosphocholine; PAF).
Specific antibodies to platelet activating factor (PAF) were prepared by immunizing rabbits with a hapten-bovine serum albumin (BSA) conjugate. As the hapten we used the synthetic PAF derivative which is resistant against enzymatic inactivation by plasma or tissues and which can bind to BSA through covalent bonding. Antibody activity was determined by an enzyme-linked immunosorbent assay (ELISA). Anti-PAF IgG reacted strongly with PAF. By means of the ELISA inhibition assay, we found that the antibody did not cross-react with phosphocholine, glycerophosphocholine, dilaurylglycerophosphocholine or PAF analogues which have ethanolamine-type polar head groups instead of choline group.
