It is not reactive with immuno-dominant A trisaccharide. This mAb is applicable for tissue staining in tumor patients with blood groups A and AB. It shows a highly heterogeneous reactivity in human colon tumor tissue and adjacent mucosa. Blood-group antigens are generally defined as molecules formed by sequential addition of saccharides to the carbohydrate side chains of lipids and proteins detected on erythrocytes and certain epithelial cells. The A, B and H antigens are reported to undergo modulation during malignant cellular transformation. 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\/li\u003e\n\u003c\/ul\u003e \u003cp\u003eWhere multiple assay formats are possible, align the antibody format, host\/isotype, and listed applications with your detection system and controls to support clear interpretation of signal.\u003c\/p\u003e \u003ch2\u003eBiological background\u003c\/h2\u003e \u003cp\u003eIn this catalog, ABO is positioned within \u003cstrong\u003eMolecular \u0026amp; Cellular Biology, Tumor\u003c\/strong\u003e research contexts.
