Abstract: | Summary The technique of ultrastructural immunocytochemistry involving the unlabeled antibody and the soluble peroxidase-antiperoxidase complex was used to identify and describe the prolactin (P) cells, somatotropic (STH) cells and luteinizing hormone (LH) cells in the bovine anterior pituitary gland. This method was used to localize the three hormones at the electron microscopic level. Staining of varying intensity was found on the secretory granules and on the small granules and vesicles within the Golgi complex. No stain was found in nuclei, on mitochondria or in the endoplasmic reticulum. |
