Summary Antisera against chromogranin A, B and C were used to study the distribution of these acidic proteins in bovine endocrine and nervous tissues. The three chromogranins occur together in several endocrine organs (adrenal medulla, anterior pituitary, endocrine pancreas) and in sympathetic ganglion cells. In the posterior pituitary, only chromogranin C and in the intermediate lobe only A and C are found. The parathyroid gland contains only A, and enterochromaffin cells are immunoreactive for A and B. Cells of the thyroid gland and some cells of the anterior pituitary apparently do not contain any chromogranins. It is concluded that the three chromogranins are not always stored together and that they are not present in all endocrine cells. This distinct localization of the chromogranins indicates some special, although still undiscovered, function for these proteins.
