Combined use of immunocytochemistry and lectin histochemistry for the study of the hypothalamic neurosecretory system of the snake Natrix maura (L.).
Natrix maura snakes were processed for immunocytochemistry and lectin histochemistry at both light- and electron-microscopic levels. Antisera against bovine neurophysins, vasotocin and mesotocin were used as well as concanavalin A, wheat germ and Limax flavus agglutinin lectins. The hypothalamic supraoptic and paraventricular nuclei were studied. Vasotocin neurons should contain a glycopeptide and displayed large colloid droplets consisting of large cisternae filled with packed secretory material. Mesotocin was located in different neurons.
