{"product_id":"nsj-v2661-20ug","title":"Keratin 7 Antibody, 20 ug","description":"\u003cp\u003eIt recognizes an intermediate filament protein (IFP) of 55kDa, which is identified as cytokeratin 7. This mAb is highly specific to cytokeratin 7 and shows no cross-reaction with other IFPs. Cytokeratin 7 is a basic cytokeratin, which is found in most glandular and transitional epithelia but not in the stratified squamous epithelia. Keratin 7 is expressed in the epithelial cells of ovary, lung, and breast but not of colon, prostate, or gastrointestinal tract. This mAb is highly useful in distinguishing ovarian carcinomas (keratin 7+) from colon carcinomas (keratin 7-).\u003c\/p\u003e","brand":"NSJ Bioreagents","offers":[{"title":"20 ug","offer_id":51549134225688,"sku":"V2661-20UG","price":259.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0590\/5652\/1400\/files\/get_image_bbc5c709-a4e9-467e-8b40-4c029af67572.jpg?v=1768292564","url":"https:\/\/danabiosci.com\/products\/nsj-v2661-20ug","provider":"Dana Bioscience","version":"1.0","type":"link"}
