{"product_id":"nsj-v3077ihc-7ml","title":"Blood Group Lewis a Antibody, 7 ml","description":"\u003cp\u003eRecognizes a carbohydrate determinant of Gal 1-3(Fuc 1-4) GlcNAc which is blood group antigen Lewis A. It is present primarily on epithelial cells such as colon and kidneys. In the tumors and dedifferentiated tissues, decrease of Lewis A antigen was observed. Lewis A (type 1 chain) is expressed in colonic epithelial cells and may be useful for detection of gastrointestinal tumors, pancreatic cancer, and colorectal tumors. Blood group related antigens represent a group of carbohydrate determinants carried on both glycolipids and glycoproteins. They are usually mucin-type, and are detected on erythrocytes, certain epithelial cells, and in secretions of certain individuals. Sixteen genetically and biosynthetically distinct but inter-related specificities belong to this group of antigens, including A, B, H, Lewis A, Lewis B, Lewis X, Lewis Y, and precursor type 1 chain antigens.\u003c\/p\u003e","brand":"NSJ Bioreagents","offers":[{"title":"7 ml","offer_id":51549037429016,"sku":"V3077IHC-7ML","price":559.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0590\/5652\/1400\/files\/get_image_74a561e4-d049-43a0-8b1e-41ea520d5bb8.jpg?v=1768290609","url":"https:\/\/danabiosci.com\/products\/nsj-v3077ihc-7ml","provider":"Dana Bioscience","version":"1.0","type":"link"}
