VALIDATION OF THE REDOX CYTOCHEMICAL ASSAY FOR CORTICOTROPHIN

Most biological assays for corticotrophin (ACTH) cannot measure normal circulating levels without the use of prohibitively large volumes of plasma. Because of its sensitivity, the redox assay (Chayen et al., 1972) is able to determine normal and subnormal ACTH concentrations in plasma using very small (microlitre) samples (Holdaway et al., 1973). In this report, measurements made with this technique have been validated by comparison with those obtained using another bioassay and two radioimmunoassays. Some study has been made of assay specificity, and data are presented supporting the assumption that the very low levels demonstrated in disease states do in fact represent intact ACTH.
