CD45R/B220 is an isoform of the CD45 protein, specifically expressed on murine B-lineage cells, including pro-B, pre-B, and mature B cells, as well as a small subset of T cells and NK cells. It is a 220 kDa surface molecule and a member of the protein tyrosine phosphatase (PTP) family, which plays a crucial role in regulating lymphocyte development and antigen receptor signaling. B220 is commonly used as a pan B-cell marker in mice due to its restricted expression on B cells, making it a valuable tool in immunological research and flow cytometry.
Flow cytometric analysis of CD45R/B220 expression on C57BL/6 mouse splenocytes. C57BL/6 mouse splenocytes were stained with Brilliant Violet 421™ Rat Anti-Mouse CD3 Antibody and either Biotin Isotype Control (Left panel) or SDT Biotin Rat Anti-Mouse/Human CD45R/B220 Antibody (Right panel) at 0.1 μg/test followed by Sav-iFluor 488. Flow cytometry and data analysis were performed using BD FACSymphony™ A1 and FlowJo™ software.
