Enzyme-linked immunosorbent assay for measurement of penicilloyl groups.


An enzyme-linked immunosorbent assay for measuring penicillin groups is described. Alkaline phosphatase conjugated to penicilloyl residue was reacted with purified anti-penicilloyl antibodies coated upon polystyrene plates. The inhibition of this reaction allowed a specific determination of penicilloyl residues at the picomole level. This assay was applied to the study of the penicilloyl groups linked to human albumin and to the measurement of some of these groups after enzymatic degradation or physical modifications of the albumin molecule.
