A competitive assay for the concentration of a cyclic nucleotide such as cyclic adenosine monophosphate combines, in a reaction chamber provided with a capture antibody, an antibody for the cAMP or other cyclic nucleotide, the sample to be assayed and a conjugate of cAMP and alkaline phosphatase. The mixture is incubated and washed, and after washing, a 1,2-dioxetane which is caused to decompose when contacted by the alkaline phosphatase of said conjugate is added. The light emission caused by decomposition is measured, with the strength of the signal being inversely related to the concentration of the cyclic nucleotide. Optionally, an enhancement agent in the form of a polymeric onium salt may be added, to further enhance the light emission.

L'invention concerne un dosage compétitif permettant de concentrer un nucléotide cyclique, ce dosage consistant par exemple à combiner un monophosphate à une adénosine cyclique dans une chambre de réaction renfermant un anticorps de capture, un anticorps de cAMP ou un autre nucléotide cyclique, l'échantillon destiné à être dosé, et un conjugué de cAMP et d'alcaline phosphatase. On fait incuber ce mélange avant de le laver, puis on y ajoute un 1,2-dioxétane qui se décompose une fois mis en présence de l'alcaline phosphatase dudit conjugué. On mesure ensuite l'émission lumineuse produite par cette décomposition, et on établit une relation inverse entre l'intensité du signal et la concentration du nucléotide cyclique. Enfin, on peut éventuellement ajouter un agent stimulant, qui se présente sous la forme d'un sel d'onium polymère, afin d'améliorer cette émission lumineuse.
