Single-chain forms of the glycoprotein hormone quartet, at least some members of which are found in most vertebrates, are disclosed. In these single-chain forms, the alpha and beta subunits of the wild-type heterodimers or their variants are covalently linked, optionally through a linker moiety. A drug may further be included within the linker moiety to be targeted to receptors for these hormones. Some of the single-chain forms are agonists and others antagonists of the glycoprotein hormone activity. Kits comprising antibodies to these proteins can be used in immunodetection methods.
