title: E-17 alpha-(2-[125I]iodovinyl)-19-nortestosterone: the synthesis of a gamma-emitting ligand for the progesterone receptor.
abstract: We have synthesized a gamma-emitting steroid, E-17 alpha-(2-[125I]iodovinyl)-19-nortestosterone (E-IVNT), which is a useful ligand for the sensitive and accurate assay of the progesterone receptor. The synthetic scheme is rapid and is performed with readily available materials. This compound, [125I]E-IVNT, is stable and binds with high affinity to the progesterone receptor.
