General Notes
Mouse anti Duck CD4 antibody, clone Du CD4-2 recognizes Pekin duck CD4, shown to be expressed by thymocytes, splenocytes and peripheral lymphoid cells. Most avian immune research has been carried out on chickens, relatively little is known about the immune system of ducks, though there is a resemblance between the main lymphoid organs, the spleen, thymus and bursa of Fabricius. At the cellular level, like mammalian T cells, duck lymphocytes are responsive to phytohaemagglutinin, and all cells reacting with clone Du CD4-2 have been identified as CD3+ T cells (Kothlow et al. 2005).Clone Du CD4-2 can be used to identify duck T helper cells. Mouse anti Duck CD4 antibody, clone Du CD4-2 does not appear to react with Mallard.
