Background

B220 is the mouse CD45 isoform CD45R, which is predominantly expressed on all B lymphocytes, including pro-, mature and activated B cells (1‑3). The level of B220 antigen expression on the B cell lineage is developmentally regulated (2‑4) and this antibody is commonly used as a B cell marker. RA3-6B2 has been reported to inhibit in vivo B cell responses (5, 6).
