MUC‑19 in Human Salivary Gland. MUC‑19 was detected in immersion fixed paraffin-embedded sections of human salivary gland using Mouse Anti-Human MUC‑19 Monoclonal Antibody (Catalog # MAB8245) at 15 µg/mL overnight at 4 °C. Tissue was stained using the Anti-Mouse HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS002) and counterstained with hematoxylin (blue). Specific staining was localized to mucosal cells.

MUC-19 is a 6,254 amino acid member of the Mucin family of gel-forming glycoproteins. MUC-19 is expressed in corneal epithelial cells in the eye, conjuctival goblet and epithelial cells and lacrimal gland cells as well as by mucous cells of the submandibular gland and submucosal gland of the trachea. MUC-19 expression is reduced in patients with Sjogren syndrome (1,2). In a middle ear model of inflammatory response, MUC-19 is up-regulated in epithelial cells by exposure to cytokines including TNF-alpha, IL-1 beta, IL-5 and IL-8 (3).
