Mouse anti Bovine CD21 monoclonal antibody, clone CC21 (MCA1424GA) used to identify ovine CD21 expressing cells in heart tissue by immunofluorescence on cryostat sections.
Image caption:
Immunofluorescence examination of explanted heart valves. CD45‐positive cells could be found within (A) allogeneic and (B) xenogeneic explants. C, Allogeneic explants exhibited the lowest number of CD45‐positive cells, whereas xenogeneic (xeno) SDS/SD‐treated explants exhibited the highest number, about 40% of all invading cells. High numbers of CD11b‐positive cells were present in all (D) allogeneic and (E) xenogeneic explants; however, (F) no significant differences were found. G, In allogeneic explants, CD3‐positive T cells were almost absent, but in (H) xenogeneic explants, a low number of CD3‐positive cells could be found. I, Enzyme‐treated valves tended to contain less CD3‐positive cells as untreated explants. J, In allogeneic as well (K) xenogeneic explants, (L) only few CD21‐positive B‐cells could be found. C, F, I, L, Every dot represents one individual animal included in the analysis. For each PHV specimen, at least two sections obtained from different areas have been analyzed, counting 11 HPFs per section. All scale bars represent 100 μm.

Mouse anti Bovine CD21 monoclonal antibody, clone CC21 recognizes the bovine CD21 cell surface antigen, a ~145 kDa single pass type I membrane glycoprotein containing multiple sushi domains. CD21 is also known as complement receptor type 2. In cattle CD21 expression is restricted to B lymphocytes (Naessens et al. 1990). CD21 may be expressed on B cells as either a long or a short form (Pringle et al. 2012)

Mouse anti bovine CD21, clone CC21 has been used to demonstrate the co-expression of CD21 with PrPc on B cells of scrapie infected sheep (Halliday et al. 2005).
