    Abstract:
    Bacterial luciferase, NAD(P): FMN oxidoreductase and anti-mouse immunoglobulin were co-immobilized on Sepharose 4B. This reagent together with a progesterone glucose-6-phosphate dehydrogenase conjugate and various anti-progesterone monoclonal antibodies was used to develop a non-separation bioluminescent immunoassay for progesterone. This monoclonal antibody based assay was sensitive and reliable and using the tracer progesterone-11-acetate-glucose-6-phosphate dehydrogenase, the majority of the monoclonal antibodies give a better sensitivity with this enzymatic tracer than that obtained with an iodinated tracer. In a second assay design progesterone-glutathione was co-immobilized with bacterial luciferase and NAD(P): FMN oxidoreductase on Sepharose 4B and three monoclonal antibodies were labelled with glucose-6-phosphate dehydrogenase. With aqueous progesterone standards, this assay gave comparable sensitivity to the bioluminescent enzyme immunoassay using the second antibody immunoadsorbent and to an RIA but was unsuitable for plasma samples.
