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).
