Abstract:
A binding assay for sex hormone binding globulin (SHBG) has been developed in which SHBG is saturated with tritiated dihydrotestosterone (DHT). Separation of bound and free DHT is achieved by using Concanavalin A-Sepharose as a solid phase matrix. The method is described and its performance, including linearity, imprecision and comparison with other methods, is assessed. The assay is simple and robust and is suitable for analysis of samples of plasma or serum for clinical or research use.
