CD1a, human (MTB1)Catalog number: CD1A-MTB
Clone MTB1 labels cortical thymocytes, Langerhans-Cells in the skin as well as interdigitating cells in the dermis and in squamous epithelia of tonsils. It labels also a small group of cells outside the germinal center of tonsils, which indicates a possible cross-reactivity with CD1b. Up to now CD1 has been identified as five different variants encoded by 5 different genes (they are designed as CD1a, b, c, d and e). CD1 is exprimed by cortical thymocytes, Langerhans cells in epithelia and dendritic cells. Usually it doesn't occur in mature peripheral blood cells, but is exprimed intra-cytoplasmatically in activated T-cells. CD1a plays a role in the detection of graft versus host reaction, in the detection of interdigitating cells in artereosclerotic lesion and in asthmatic inflammation. Human CD1a, possible cross-reactivity with CD1b.
