Anti-HMW Cytokeratin, clone 34BE12

1 mg/ml in sterile PBS, BSA free, sodium azide free. This antibody recognizes HMW Cytokeratin 1, 5, 10 and 14. In normal epithelia, it stains stratified epithelia, myoepithelial cells and basal cells in the prostate gland and bronchi. The HMW Cytokeratin antibody shows no reactivity with hepatocytes, pancreatic acinar cells, proximal renal tubules, or endometrial glands, there is no reactivity with cells derived from simple epithelia. Mesenchymal tumors, lymphomas, melanomas, neural tumors, and neuroendocrine tumors are negative with this mAb. It stains myoepithelial cells and has been shown to be useful in distinguishing prostate adenocarcinoma from benign prostate. It has also been useful in separating benign from malignant intraductal breast proliferations. Protein function: May regulate the activity of kinases such as PKC and SRC via binding to integrin beta-1 (ITB1) and the receptor of activated protein kinase C (RACK1/GNB2L1). In complex with C1QBP is a high affinity receptor for kininogen-1/HMWK. [The UniProt Consortium]
