Abstract:
:The synthesis and in vitro biological activity of a hybrid protein composed of intact human chorionic gonadotropin and fragment A of diphtheria toxin in a disulfide conjugate is reported. This hybrid retained greater than 90% of the binding ability of uncoupled hCG and was shown to be specifically toxic to a mouse Leydig cell tumor which binds hCG while being non-toxic towards cells which lack receptors for hCG.
