Clone Host Grade Applications
Monoclonal Mouse Supernatant B IH IF
Keratin 4, which belongs to the type B (II) (basic) subfamily of high molecular weight keratins and exists in combination wth cytokeratin 13. It is primarily found in the non-cornifying squamous epithelium e.g. superficial and intermediate epithelial cells of the esophagus, ectocervix, toungue, vagina, larynx, pharynx, epiglottis, anus and the superficial cells of the cornea. Keratin 4 is also present in the suprabasal cells of the urinary bladder transitional epithelium in single cells and cell groups of sweat glands, prostatic ducts and in cylindrical ciliated bronchial epithelial cells. Keratin 4 may be detected in squamous cell carcinomas derived from several non-cornified stratified epithelia.
