General Notes
Mouse anti Bovine CD5 antibody, clone CC15 recognizes bovine CD5, a ~67 kDa type 1 single pass transmembrane molecule containing three scavenger receptor cysteine rich (SRCR) domains. Clone CC17 reacts with BoCD5.1, which is a polymorphic antigen expressed on cells of all Bos taurus animals and a small proportion of Bos indicus animals.Bo5.1, recognized by Mouse anti Bovine CD5, clone CC17 is the only isoform expressed by Bos taurus while Bos indicus may express Bo5.2 or both allelic forms of bovine CD5. (Howard et al.1989) .Bovine CD5 is expressed by all mature T-lymphocytes and a subpopulation of B-lymphocytes. It is also expressed by mature medullary thymocytes and at a lower level by immature cortical thymocytes (Howard et al. 1988).
