{"product_id":"r31920","title":"Cytokeratin 19 Antibody","description":"\u003cp\u003eCytokeratin 19, also called Keratin 19 and CK19, 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, CK19 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 \/ Rabbit","offer_id":49476725309720,"sku":"R31920","price":439.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0590\/5652\/1400\/files\/get_image_2da8b6ff-465c-46c5-9642-61632bac7d28.jpg?v=1734480854","url":"https:\/\/danabiosci.com\/products\/r31920","provider":"Dana Bioscience","version":"1.0","type":"link"}
