It uses our proprietary SimpleStep ELISA® technology. Quantitate Human Cytokeratin 19 with 375 pg\/ml sensitivity.\u003cbr\u003e\nSimpleStep ELISA® technology employs capture antibodies conjugated to an affinity tag that is recognized by the monoclonal antibody used to coat our SimpleStep ELISA® plates. This approach to sandwich ELISA allows the formation of the antibody-analyte sandwich complex in a single step, significantly reducing assay time. See the SimpleStep ELISA® protocol summary in the image section for further details. Our SimpleStep ELISA® technology provides several benefits:\u003cbr\u003e\n- Single-wash protocol reduces assay time to 90 minutes or less\u003cbr\u003e\n- High sensitivity, specificity and reproducibility from superior antibodies\u003cbr\u003e\n- Fully validated in biological samples\u003cbr\u003e\n- 96-wells plate breakable into 12 x 8 wells strips\u003cbr\u003e\nA 384-well SimpleStep ELISA® microplate (\u003cbr\u003e\nab203359\u003cbr\u003e\n) is available to use as an alternative to the 96-well microplate provided with SimpleStep ELISA® kits.\u003cbr\u003e\nCytokeratin 19, also known as KRT19, is an intermediate filament protein that gives structure to epithelial cells. Beyond its role as a structural protein, KRT19 is involved in cell signaling pathways including Wnt\/Notch and EGR1\/PTEN\/AKT, although the response to altered expression is highly cell-type dependent. Expression levels of this protein are altered in many types of cancers, and it is currently used as a biomarker for breast cancer.The standard is affinity purified.\u003cbr\u003e\nREACH authorisation\u003cbr\u003e\nAbcam has not and does not intend to apply for the REACH Authorisation of customers' uses of products that contain European Authorisation list (Annex XIV) substances.\u003cbr\u003e\nIt is the responsibility of our customers to check the necessity of application of REACH Authorisation, and any other relevant authorisations, for their intended uses.\u003c\/p\u003e\n\n\u003cp\u003eProperties and Storage Information:\u003cbr\u003e\nShipped at conditions-Blue Ice, Appropriate short-term storage conditions-+4°C, Appropriate long-term storage conditions-+4°C, Storage information-+4°C\u003c\/p\u003e\n\n\u003cp\u003eSupplementary Information:\u003cbr\u003e\nThis supplementary information is collated from multiple sources and compiled automatically.\u003cbr\u003e\nCytokeratin 19 (CK19) also known as cytokera­tine 19 keratin 19 (KRT19) or CK19 is a type of intermediate filament found in epithelial cells. It serves as an essential component of the cytoskeleton. CK19 weighs approximately 40 kDa and is broadly expressed in simple epithelial tissues including liver intestine and various glandular epithelial cells. As a cytokeratin marker it often appears in combination with others like cytokeratin 17 in certain tissue types helping to maintain the structural integrity of cells.\u003cbr\u003e\nBiological function summary\u003cbr\u003e\nCK19 plays a role in maintaining the cytoskeletal framework that provides mechanical support and helps control cell size and shape. It is not part of a large protein complex but works closely with other cytokeratins to ensure the stability and resilience of epithelial tissues. The A53-B\/A22.26 positive staining is often used to confirm its presence in clinical histopathology.\u003cbr\u003e\nPathways\u003cbr\u003e\nCK19 connects to cellular processes especially involving the keratinization and epithelial cell differentiation pathways. It interacts with other cytokeratins including BA16 and KR17 to facilitate these processes. This interaction aids in modulating the dynamics of cytoskeletal rearrangement during cell movement division and differentiation.\u003cbr\u003e\nCK19 overexpression is linked with certain cancers notably hepatocellular carcinoma and breast cancer. It can serve as a prognostic marker in these diseases often in conjunction with other markers like CK17. The involvement of CK19 in the epithelial-mesenchymal transition (EMT) process connects it to the progression and aggressiveness of tumors facilitated by interactions with proteins involved in EMT pathways.\u003c\/p\u003e","brand":"Abcam","offers":[{"title":"Default Title","offer_id":46843539194025,"sku":"ab252367","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/abcam-ab252367","provider":"Iright","version":"1.0","type":"link"}
