CD43 antibody recognizes a 95/115/135kDa (depending upon the extent of glycosylation) cell surface glycoprotein, identified as CD43 (leukosialin, sialophorin, or leukocyte sialoglycoprotein) CD43 is shown to be expressed on all thymocytes, T-cells and in endothelial cells. CD43 may also aid in distinguishing extranodal marginal zone B-cell lymphoma from other reactive processes in the skin. The CD43 antibody has also been shown to be useful in aiding in the identification and classification of T-cell malignancies and low-grade B-cell lymphomas.
