Monoclonal antibody 6D4 reacts with MICA and MICB, distant homologs of major histocompatibility complex class I proteins. They are highly glycosylated molecules of approximately 70 kDa that are normally expressed in gut epithelium, are frequently associated with epithelial tumors and can be induced by some viral and bacterial infections. MIC are highly expressed on proliferating but not on quiescent epithelial cell lines, on which they can be heat-shock induced. MIC have similar functional and structural properties and are ligands for NKG2D, an activating receptor on most NK cells, CD8 T cells and ?d T cells. Expression of MIC has been observed on synoviocytes in rheumatoid arthritis and on epithelial cells in transplanted kidney and pancreas showing histological signs of rejection and or cellular injury. Profile of anti MIC A/B (clone 6D4) reactivity on HeLa cells analyzed by flow cytometry. Second step staining with Cat. No. 550589.
