| Background Information | Mucin-4 (MUC-4 or Muc4) is also called Ascites sialoglycoprotein (ASGP), Pancreatic adenocarcinoma mucin, Testis mucin, and Tracheobronchial mucin. Muc4 is proteolytically cleaved into two chains: mucin-4 alpha chain and mucin-4 beta chain. Muc4 has anti-adhesive properties and is involved in tumor progression, cell proliferation and differentiation of epithelial cells. Muc4 is expressed in the thymus, thyroid, lung, trachea, esophagus, stomach, small intestine, colon, testis, prostate, ovary, uterus, placenta, mammary and salivary glands as well as lung cancers, squamous cell carcinomas of the upper aerodigestive tract, mammary carcinomas, biliary tract, colon, cervix cancers, pancreatic tumors, and pancreatic tumor cell lines. The expression of Muc4 has become a very useful indicator of poor prognosis in patients with invasive ductal carcinoma and intrahepatic cholangiocarcinoma, mass forming type (IDC,ICC-MF), where patients with high Muc4 expression had lower survival rates than those with low Muc4 expression. |

| Application Notes | Immunohistochemistry Analysis: A 1:2,000 dilution from a representative lot detected Muc4 in human ilium tissues. Western Blotting Analysis: A representative lot from an independent laboratory detected Muc4 in maligant melanoma and cutaneous squamous cell carcinoma tissue lysates (Moniaux, N., et al. (2004). J Histochem Cytochem. 52(2):253-261.). Immunohistochemistry Analysis: A representative lot from an independent laboratory detected Muc4 in lung adenocarcinoma and pancreatic adenocarcinoma tissues (Moniaux, N., et al. (2004). J Histochem Cytochem. 52(2):253-261.). Immunohistochemistry Analysis: A representative lot from independent laboratories detected Muc4 in 330 tissue spots representing normal skin, and benign and malignant cutaneous diseases (Singh, A. P., et al. (2006). Prostate. 66(4):421-429.; Chakraborty, S., et al. (2010). J Clin Pathol. 63(7):579-584.). |
