Cytokeratin 5 (Cytokeratin-5, CK 5, CK5, CK-5, 58kD Cytokeratin, DDD, EBS 2, EBS2, Keratin 5 (Epidermolysis Bullosa Simplex Dowling Meara/Kobner/Weber Cockayne Types), Keratin-5, Keratin Type II Cytoskeletal 5, K5, KRT5, KRT5A)

Cytokeratins (CK) are intermediate filaments of epithelial cells, both in keratinising tissue (ie., skin) and non keratinising 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 (CK) in the molecular range of 40 to 70kD and isoelectric points of 5 to 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. Defects in KRT5 are a cause of epidermolysis bullosa simplex.\n\nCellular Localization: Cytoplasmic\n\nPositive Control: Skin\n\nApplications: \nSuitable for use in Immunohistochemistry. Other applications not tested.\n\nRecommended Dilution:\nOptimal dilutions to be determined by the researcher.\n\nStorage and Stability:\nMay be stored at 4 degrees C for short-term only. For long-term storage and to avoid repeated freezing and thawing, aliquot Store at -20 degrees C. Aliquots are stable for at least 12 months at -20 degrees C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.

Additional Info

This antibody reacts with cytokeratin 5 intermediate filament protein. Basal cells of human epidermis express acidic cytokeratin 14 and basic cytokeratin 5. Cytokeratin 5 is a 58kD protein, which is closely related to cytokeratin 6. Cytokeratin 5 and 6 are expressed in basal cell epithelioma, basal cells of prostate, urothelium, vagina, squamous cell carcinomas of skin, tongue, epiglottis and rectal-anal region. cytokeratin 5 can be useful in the distinction of mesotheliomas from most adenocarcinomas. Species Crossreactivity: This antibody is reactive against human.
