Background
Cytokeratins (CK) are intermediate filaments of epithelial cells, both in keratinizing tissue (ie., skin) and non-keratinizing cells (ie., mesothelial cells). Although not a traditional marker for endothelial cells, cytokeratins have also been found in some microvascular endothelial cells. At least 20 different cytokeratins in the molecular range of 40-70 kDa and isoelectric points of 5-8.5 can be identified using two dimensional gel electrophoresis. Biochemically, most members of the CK family fall into one of two classes, type I (acidic polypeptides) and type II (basic polypeptides). At least one member of the acidic family and one member of the basic family is expressed in all epithelial cells. Monoclonal antibodies to cytokeratin proteins can be useful markers for tumor identification and classification.

Product
Product Form: Unconjugated
Formulation: Provided as solution in phosphate buffered saline with 0.08% sodium azide
Purification Method: Purified by saturated ammonium sulphate precipitation
Concentration: See vial for concentration
Applications
X1260M detects keratins 4,5,6,8,10,13 & 18 by Western blot. Immunohistochemistry can be performed on frozen tissues and paraffin sections. Optimal concentration should be evaluated by serial dilutions.
X1260M reacts with a variety of normal and neoplastic epithelia. Reacting with simple epithelium and both basal and superbasal layers of cornifying and non-cornifying squamous epithelium this antibody is also useful in staining cultured epithelial cell lines. It is useful in differentiating epithelial tumors from non-epithelial tumors.
