A method for radioimmunological assay of glisoxepide (author's transl). 1976

B Nieuweboer, and D Gabriel, and K Lübke

A radioimmunoassay for the antidiabetic drug 3-(4-[beta-(5-methyl-isoxazol-3-carboxyamido)-ethyl]-benzenesulfonyl)-ureido-piperidine-4-carboxic acid (glisoxepide, I, Pro-Diaban) is described. Antisera were obtained by immunizing rabbits with a piperidine carboxylic acid analogue of glisoxepide coupled to bovine serum albumine. The carboxylic acid analogue coupled to [3H]-1-tyrosine methyl ester was used as the tracer. Antisera with high sensitivity were obtained. With some glisoxepide analogues the specificity of the antisera was investigated. For good binding the isoxazole and the benzene ring as well as the appropriate distance between both rings are essential. The assay can be carried out without extraction of the compound from the serum. Dextran coated charcoal is used for separation of free and bound glisoxepide.

D011863 Radioimmunoassay Classic quantitative assay for detection of antigen-antibody reactions using a radioactively labeled substance (radioligand) either directly or indirectly to measure the binding of the unlabeled substance to a specific antibody or other receptor system. Non-immunogenic substances (e.g., haptens) can be measured if coupled to larger carrier proteins (e.g., bovine gamma-globulin or human serum albumin) capable of inducing antibody formation.
