{"product_id":"new-product-567360","title":"Cytokeratin 19 Polyclonal Antibody","description":"\u003cp\u003eKeratin type I cytoskeletal 19 encoded by KRT19 is a member of the keratin family. 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. The type I cytokeratins are clustered in a region of chromosome 17q12-q21.\u003c\/p\u003e\n\u003cp\u003eThe Cytokeratin 19 Polyclonal Antibody is a highly specific and sensitive tool designed for the detection and analysis of Cytokeratin 19 (CK19) protein expression. This antibody is produced through a rigorous process, ensuring its high quality and reliability in various applications, including immunohistochemistry (IHC), western blotting, and immunofluorescence (IF).\u003cbr\u003e\u003cbr\u003eCK19 is a member of the intermediate filament family of proteins and is predominantly expressed in epithelial cells. It plays a crucial role in maintaining the structural integrity of epithelial tissues and is widely used as a marker for epithelial cell identification and differentiation. The Cytokeratin 19 Polyclonal Antibody recognizes CK19 with exceptional specificity, enabling accurate and precise detection of CK19 expression in various biological samples.\u003cbr\u003e\u003cbr\u003eThis antibody exhibits excellent sensitivity, allowing for the detection of low levels of CK19 expression. Its high affinity for CK19 ensures reliable and reproducible results, making it an ideal choice for both qualitative and quantitative analysis. The Cytokeratin 19 Polyclonal Antibody demonstrates minimal cross-reactivity with other cytokeratin isoforms, further enhancing its specificity and reducing the risk of false-positive results.\u003cbr\u003e\u003cbr\u003eIn addition to its exceptional performance, this antibody is also highly versatile. It is compatible with a wide range of sample types, including formalin-fixed paraffin-embedded (FFPE) tissues, frozen sections, and cell cultures. Its compatibility with multiple detection methods, such as IHC, western blotting, and IF, allows for flexibility in experimental design and facilitates comprehensive analysis of CK19 expression.\u003cbr\u003e\u003cbr\u003eThe Cytokeratin 19 Polyclonal Antibody is supplied in a convenient and ready-to-use format, ensuring ease of use and saving valuable time in the laboratory. It is provided in a liquid formulation, eliminating the need for reconstitution and minimizing the risk of errors during preparation. The antibody is also available in various sizes to accommodate different experimental needs.\u003cbr\u003e\u003cbr\u003eIn summary, the Cytokeratin 19 Polyclonal Antibody is a highly reliable and specific tool for the detection and analysis of CK19 protein expression. Its exceptional sensitivity, versatility, and ease of use make it an indispensable asset for researchers and clinicians working in the field of epithelial cell biology and pathology.\u003c\/p\u003e","brand":"BT Lab","offers":[{"title":"100ul \/ Rabbit \/ Primary antibody","offer_id":47541345747224,"sku":"BT-AP02472","price":275.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0590\/5652\/1400\/products\/BT_Lab_896bf267-487e-4bc1-8c04-f9e6eeaaf0bb.png?v=1705617961","url":"https:\/\/danabiosci.com\/products\/new-product-567360","provider":"Dana Bioscience","version":"1.0","type":"link"}
