Anti-CD21 [THB-5]

This antibody is specific for human CD21 (complement receptor type 2), which is expressed on B-cells and participates in B cell activation. It recognises a distinct antigenic site to the anti-B2 antibody (Tedder et al, 1984).

The binding specificity of this antibody has been confirmed in flow cytometry and immunofluorescence analysis (Tedder et al, 1984), with only B cell reactivity observed. Though this antibody binds to CD21, which acts as a receptor for Epstein-Barr virus (EBV), it cannot alone block viral entry into B cells (Fingeroth et al, 1984). EBV virions engineered to express this antibody at their surface have been used to probe the need for CD21 binding to achieve viral entry (Busse et al, 2010).
