Specifications for CD43 Antibody, anti-mouse, REAfinity™


Clone REA840 recognizes the mouse CD43 antigen, a glycosylated protein also known as leukosialin or sialophorin, which is expressed on IL-7–responsive pro–B cells, plasma cells, peritoneal and spleen CD5
B cells (B-1 cells), granulocytes, monocytes, macrophages, platelets, NK cells, thymocytes, peripheral cytotoxic T cells, and most T helper cells. CD43 is not expressed on resting conventional peripheral B cells. Thus, resting B cells are easily identified by the lack of CD43 expression.
Additional information: Clone REA840 displays negligible binding to Fc receptors.
