Abstract
Tritiated .beta.-endorphin is prepared by catalytic tritiation of a [3,5-diido-Tyr]-.beta.-endorphin which in turn is readily obtained by solid phase synthesis. The tritiated .beta.-endorphin preferably [3,5-diiodo-Tyr.sup.27 ]-.beta.-endorphin may be utilized as a radio-labelled tracer compound in radioimmunoassay for .beta.-endorphin and also exhibits biological activity comparable to that of the native .beta.-endorphin.
