ABSTRACT
cAMP measurements are obtained using an ELISA assay (Harlow and Lane 1988). Commercial radio-immunoassays, or
ELISA kits, to assay cAMP can be purchased from various manufacturers. In our laboratory we use the homemade,
less-expensive ELISA that is described below. In outline, this assay is based on the ability of soluble cAMP in
bacterial extracts to compete with binding of an alkaline phosphatase (AP)-conjugated anti-cAMP antibody to
immobilized cAMP. The surface-bound, immobilized anti-cAMP-AP is inversely correlated to the concentration of
cAMP in the extract. Known concentrations of soluble cAMP are used to calibrate the assay. |
