{"product_id":"nsj-v3077-100ug","title":"Blood Group Lewis a Antibody, 100 ug","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":"100 ug","offer_id":51549037494552,"sku":"V3077-100UG","price":559.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0590\/5652\/1400\/files\/get_image_b8a4e8b6-3f84-47a0-b6b8-00e662122e01.jpg?v=1768290612","url":"https:\/\/danabiosci.com\/products\/nsj-v3077-100ug","provider":"Dana Bioscience","version":"1.0","type":"link"}
