An indirect ELISA for urinary gonadotropins using immobilized human menopausal gonadotropin.
An indirect ELISA for the estimation of urinary gonadotropins is described. Human menopausal gonadotropin is adsorbed on a microtitre plate, where it serves as an immunosorbent. The residual antigonadotropin antibody is captured by the immunosorbent after reaction with the sample or standard and detected with enzyme-labelled antispecies antibody (antirabbit gamma-globulin-horse radish peroxidase). The assay developed here is rapid and satisfies usual validatory criteria expected from an immunoassay. Moreover, it obviates the need for extraction of samples with acetone, as shown by the close agreement between the respective lutropin or follitropin concentrations in extracted and unextracted urine samples.
