{"product_id":"cytokeratin-17-antibody-bha17118800","title":"Cytokeratin 17 Antibody","description":"\u003ch2\u003eOverview\u003c\/h2\u003e\u003cp\u003eCytokeratin 17 (CK17) is a member of the Cytokeratin subfamily of intermediate filament proteins (IF's). It is unique in that it is normally expressed in the basal cells of complex epithelia but not in stratified or simple epithelia. CK17 is expressed in the nail bed, hair follicle, sebaceous glands and other epidermal appendages. Antibody to CK17 is an excellent tool to distinguish myoepithelial cells from luminal epithelium of various glands such as mammary, sweat and salivary. CK17 is expressed in epithelial cells of various origins, such as bronchial epithelial cells and skin appendages. It may be considered an epithelial stem cell marker because CK17 Ab marks basal cell differentiation. CK17 can be useful when included in a panel of antibodies against TTF-1, napsin A, CK5\u0026amp;6, p63, and SOX-2 for diagnostic differentiation between lung adenocarcinoma (LADC) and lung squamous cell carcinoma (SCLC), especially for poorly-differentiated lung carcinoma. CK17 is expressed in SCLC much higher than in LADC. In breast carcinomas, approximately 20% of patients show no expression of ER, PR and Her2, which are defined as triple negative tumor. Eighty-five percent of the triple negative breast carcinomas immunoreact with basal cytokeratins including anti-CK17. Also important is that cases of triple negative breast carcinoma with expression of CK17 show an aggressive clinical course. The histologic differentiation of ampullary cancer, intestinal vs. pancreatobiliary, is very important for treatment. Usually anti-CK17 and anti-MUC1 immunoreactivity represents pancreatobiliary subtype whereas anti-MUC2 and anti-CDX-2 positivity defines intestinal subtype.\u003c\/p\u003e\u003cp\u003eThis anti-Cytokeratin 17 antibody is supplied as Purified (Mouse, Monoclonal (mouse origin), clone SPM560, Mouse IgG2b, kappa, Unconjugated) and is designed to support common target-detection workflows after the on-page specifications.\u003c\/p\u003e\u003ch2\u003eKey elements and design rationale\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTarget:\u003c\/strong\u003e Cytokeratin 17\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFormat:\u003c\/strong\u003e Purified\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLocalization:\u003c\/strong\u003e Cytoplasmic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecies reactivity:\u003c\/strong\u003e Human\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplications (listed):\u003c\/strong\u003e FACS, IHC-P, WB\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConjugate:\u003c\/strong\u003e Unconjugated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClone and antibody class:\u003c\/strong\u003e Monoclonal (mouse origin), clone SPM560, Mouse IgG2b, kappa\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eBecause antibody performance can depend on epitope context, sample preparation, and biological state, interpret signals using appropriate controls and orthogonal evidence when possible.\u003c\/p\u003e\u003ch2\u003eBiological background\u003c\/h2\u003e\u003cp\u003eCytokeratin 17 is referenced in public gene\/protein resources (e.g., UniProt and NCBI Gene), which provide curated names\/synonyms, protein features, and pathway context.
