General description

Cytokeratins are proteins of keratin-containing intermediate filaments that provide mechanical support and other additional functions in epithelial cells. It is found in the intracytoplasmic cytoskeleton of epithelial tissue. Epithelial tissue expresses cytokeratin subunits in a specific and stable pattern. Cytokeratins along with vimentin are involved in cell proliferation, migration and differentiation of preodontoblasts and preameloblasts. The intermediate-sized filaments are abundant in human endothelial cells and are mostly of vimentin type.

FITC Monoclonal Anti-Pan Cytokeratin is a purified mouse monoclonal antibody conjugated with fluorescein isothiocyanate (FITC) isomer I. Monoclonal anti-pan cytokeratin (mouse IgG1 isotype) is derived from the PCK-26 hybridoma produced by the fusion of mouse myeloma cells and splenocytes of immunized BALB/c mice. Cytokeratins, a group comprised of at least 29 different proteins are characteristic of epithelial and trichocytic cells. Cytokeratin 5, 6 and 8 are members of the type II, neutral-to-basic subfamily. Cytokeratin peptide 5 is the primary type II keratin in stratified epithelia while cytokeratin type 8 is a major type II keratin in simple epithelia. Cytokeratin 6 is a "hyperproliferation" cytokeratin expressed in tissues with natural or pathological high turnover.


The antibody recognizes an epitope located on the Type II cytokeratins 1, 5, 6, and 8. PCK-26 is a broad spectrum antibody which reacts specifically with a variety of normal, reactive, and neoplastic epithelial tissues. The antibody reacts with simple, cornifying, and non-cornifying squamous epithelia and pseudostratified epithelia.
