Popis: A specific and sensitive β-galactosidase immunoassay is described. A cyclic AMP-β-galactosidase conjugate is used as the labeled cyclic AMP derivative in a competitive binding assay. By determining the β-galactosidase activity, the concentration of the antibody-bound conjugate is easily detected. Cyclic AMP levels and adenylate cyclase activities in Escherichia coli K12 can be determined by using this β-galactosidase immunoassay. Comparative studies performed between this enzyme immunoassay and the conventional radioimmunoassay show satisfactory correlation between the two methods.
