title: An enzyme-linked immunoassay of testosterone.
abstract: An enzyme-linked immunoassay of testosterone is described. The conjugation of testosterone with high specific activity horseradish per-oxidase and a highly sensitive assay for this enzyme having previously been studied, here we describe the immobilization of the anti-testosterone antibody and the development of assay conditions permitting the determination of 50 pg to 1.5 ng testosterone in one working day. In this work attention has been paid to keeping the assay method as simple as possible. The method is discussed in terms of other enzyme-linked immunoassays for steroids.
