Preparation and properties of tritiated human beta-endorphin with high specific radioactivity.
Tritiated human beta-endorphin, specifically labelled at Tyr27, has been prepared with 50 Ci/mmol. Various physicochemical investigations indicated that tritiated peptide is identical with the native betah-endorphin. In addition, opiate activity of the tritiated product possesses the same potency as the native peptide.
