{"product_id":"rq4521","title":"Cytokeratin 19 Antibody","description":"\u003cp\u003eKeratin, type I cytoskeletal 19 is a protein that in humans is encoded by the KRT19 gene. The protein encoded by this gene is a member of the keratin family. It is specifically expressed in the periderm, the transiently superficial layer that envelops the developing epidermis. The type I cytokeratins are clustered in a region of chromosome 17q12-q21. Due to its high sensitivity, KRT19 is the most used marker for the RT-PCR-mediated detection of tumor cells disseminated in lymph nodes, peripheral blood, and bone marrow of breast cancer patients. Keratin 19 is often used together with keratin 8 and keratin 18 to differentiate cells of epithelial origin from hematopoietic cells in tests that enumerate circulating tumor cells in blood.\u003c\/p\u003e","brand":"NSJ Bioreagents","offers":[{"title":"100 ug \/ Mouse","offer_id":49476114907416,"sku":"RQ4521","price":439.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0590\/5652\/1400\/files\/get_image_54f90358-ee6e-47c1-a7bd-f7093909ce8b.jpg?v=1734467513","url":"https:\/\/danabiosci.com\/products\/rq4521","provider":"Dana Bioscience","version":"1.0","type":"link"}
