The keratins are intermediate filament proteins responsible for the structural integrity of epithelial cells and are subdivided into cytokeratins and hair keratins. The type I cytokeratins consist of acidic proteins which are arranged in pairs of heterotypic keratin chains. Unlike its related family members, this smallest known acidic cytokeratin is not paired with a basic cytokeratin in epithelial cells. It is specifically expressed in the periderm, the transiently superficial layer that envelopes the developing epidermis. Keratin 19 is not expressed in hepatocytes, therefore, antibody to keratin 19 is usefμl in the identification of liver metastasis. The degree of keratin 19 positivity in breast cancer distinguishes malignant from benign tumours. Keratin 19 is often co-expressed with keratin 7.\u003c\/p\u003e\n\n\u003cp\u003eCategory: Primary Antibody\u003c\/p\u003e\n\n\u003cp\u003eReactivity: Human, Mouse, Rat\u003c\/p\u003e\n\n\u003cp\u003eHost: Rabbit\u003c\/p\u003e\n\n\u003cp\u003eApplications: WB, IHC\u003c\/p\u003e\n\n\u003cp\u003eAlternate Names: Keratin, type I cytoskeletal 19, Cytokeratin-19, CK-19, Keratin-19, K19, KRT19\u003c\/p\u003e\n\n\u003cp\u003eClonality: Polyclonal\u003c\/p\u003e\n\n\u003cp\u003eConjugate: Unconjugated\u003c\/p\u003e\n\n\u003cp\u003eModification: Unmodification\u003c\/p\u003e\n\n\u003cp\u003eImmunogen: Synthetic peptide, corresponding to amino acids 321-370 of Human Cytokeratin 19.\u003c\/p\u003e\n\n\u003cp\u003eDilution: WB: 1:500~1:1000\u003cbr\u003e\nIHC: 1:50~1:200\u003c\/p\u003e\n\n\u003cp\u003ePurification: The antibody was affinity-purified from rabbit antiserum by affinity-chromatography using epitope-specific immunogen and the purity is \u0026gt; 95% (by SDS-PAGE).\u003c\/p\u003e\n\n\u003cp\u003eSpecificity: Cytokeratin 19 (L349) polyclonal antibody detects endogenous levels of Cytokeratin 19 protein.\u003c\/p\u003e\n\n\u003cp\u003eMolecular Weight: ~ 44 kDa\u003c\/p\u003e\n\n\u003cp\u003ePathway: Contribution of Soluble Factors to EMT,\u003c\/p\u003e \n\n\u003cp\u003eStorage and Stability: Store at 4°C short term.
