The HECA-452 monoclonal antibody specifically reacts with Cutaneous Lymphocyte Associated Antigen (CLA), a carbohydrate domain shared by sialyl Lewis[x] (sLe[x]) and sialyl Lewis[a] (sLe[a]) antigens. It serves as a ligand for selectins including CD62E (E-selectin, ELAM-1). CLA is expressed on high endothelium and on lymphocytes including most T lymphocytes infiltrating cutaneous sites of inflammation. Amongst peripheral blood cells, it is expressed on monocytes and granulocytes and a subset of lymphocytes. The HECA-452 antibody is also reportedly crossreactive with the mouse CLA carbohydrate epitope that is transiently expressed by PSGL-1/CD162 on activated T cells. A number of studies suggest that CLA plays an important role in supporting leucocyte adhesive interactions and migration into extravascular tissues during inflammation. Immunohistochemical staining of endothelial cells with CLA. Frozen section of human tonsil was stained with Purified Rat Anti-Human Cutaneous Lymphocyte Antigen (Cat. No. 550407) antibody. Endothelial cells of the high endothelial vessels can be identified by the intense brown labeling of their cell surface membranes. Amplification 40x.
