Specifications for CD21/CD35 Antibody, anti-mouse, REAfinity™


Clone REA800 recognizes an epitope shared by mouse CD21 and CD35, also known as CR2 and CR1. CD21 and CD35 are alternatively spliced transcripts from the Cr2 gene, which produce cell-surface proteins of 145 and 190 kDa, respectively. CD21 and CD35 are expressed on the majority of peripheral B lymphocytes, on the majority of resident peritoneal macrophages, on mast cells, activated granulocytes, and follicular dendritic cells. CD21 forms part of a signal transduction complex with CD19 and CD81, which are associated with the antigen receptor on B lymphocytes.
Additional information: Clone REA800 displays negligible binding to Fc receptors.
