title: Enzyme linked immunosorbent assay (ELISA) for beta-endorphin and its antibodies.
abstract: A sensitive method for quantitation of beta-endorphin in biological fluids and tissues using ELISA methodology has been developed. This assay is sensitive to as low as 30 picograms of beta-endorphin per measurement and can be carried out in approximately 5 hours. The determination of antibody titer levels to beta-endorphin can also be quantitated using a modified double sandwich ELISA.
