title: A specific, sensitive and high-capacity immunoassay for PAF.
abstract: A specific radioimmunoassay for platelet-activating factor (PAF) sensitive in the range 10-1000 pg (0.02-2 pmoles) has been developed. Detailed quantitative hapten inhibition studies showed specificity for the acetyl group at C-2 of PAF, a requirement for the ether linkage at C-1 and some tolerance for substituents on the choline nitrogen. No significant cross-reactivity was found with phosphatidylcholine and lysophosphatidylcholine or with lysoPAF.
