CD45R (B220) antibodies, mouse

Clone: RA3-6B2 | Dilution: 1:50
Clone RA3-6B2 recognizes the mouse CD45R (B220) antigen which is expressed on B lymphocytes throughout their development from early pro–B stages onwards and is down-regulated upon terminal differentiation to plasma cells. Apart from B cells, CD45R is expressed on a small subset of dendritic cells (plasmacytoid dendritic cells). The CD45R monoclonal antibody clone RA3-6B2 specifically recognizes the exon A–restricted isoform of mouse CD45. CD45R is absent in thymus but reported to be present on apoptotic thymocytes.
