ULTRASTRUCTURAL LOCALIZATION OF LYSOZYME IN THE HUMAN NASAL GLAND BY PROTEIN A-GOLD TECHNIQUE

Abstract

The ultrastructural localization of lysozyme was studied using the protein A-gold technique in the human nasal gland. There was much in the secretory granules of the serous cells, but not in the mucous cells. Some granules of the serous cells had a central core, and these had more lysozyme. Much lysozyme was also found in the secretory material within the glandular lumen in forms associated with a central core or in amorphous secretion, suggesting its protective role here against bacterial infection.
