A battery of antibodies directed against different portions of the precursor to gonadotropin-releasing hormone (GnRH), as well as to the mature decapeptide, were characterized immunocytochemically in two ways. Absorption experiments were used to determine the epitope recognized by each antiserum. Electron microscopic immunocytochemistry was then used to define the subcellular organelles that contained reaction product when tissue was incubated with these reagents. These latter observations helped to determine if the antibody recognized the epitope as part of the intact precursor or only after it had been cleaved from parent protein. Our results demonstrate that the GnRH precursor is routed from the rough endoplasmic reticulum through the Golgi apparatus to the secretory vesicles. Furthermore, we show that initial cleavage and processing of the GnRH precursor begin in the cell soma. These antibodies should be useful in the future in determining changes in processing of precursor in animals that differ in endocrine function.
