Mouse anti Duck IgY Light Chain antibody, clone 14A3 recognizes the light chain of duck immunoglobulin, shown to be expressed strongly on bursal cells and weakly on splenocytes and peripheral lymphoid cells, but not expressed by thymocytes.

Double-staining with clone 14A3 and duck CD8 alpha clone Du CD8-1 (product code MCA2479), revealed the presence of a CD8high /14A3- cytotoxic T cell population and a CD8low/14A3+ B cell population in duck spleen and also revealed a high percentage of CD8+ /14A3+ cells in duck bursa (Kothlow et al. 2005). The recognition of B cells by 14A3 was confirmed using a recently developed Flag-tagged chicken B cell marker, known as chBAFF-Flag (B cell activating factor).

Mouse anti Duck IgY Light Chain antibody, clone 14A3 recognizes IgA in Pekin duck bile and can be used as a marker to identify B cells in both Pekin and Muscovy duck and geese studies.

Mouse anti Duck IgY Light Chain antibody, clone 14A3 detects a band of approximately 25 kDa in duck cell lysates in Western blotting.
