Using these antisera, the B-and T-cell populations of lymphoid organs of chickens at different times after hatching have been delineated (4). The present report summarizes experimental results on the appearance and frequency of cells bearing antigenic determinants defined by anti

IgA Surface Determinants on Cells from the Chicken Embryoproduced using serum, bile or oviduct washings as antigen source in rabbits (1–3) or pheasants (4). IgA is present in chicken serum and secretions in a variety of polymer molecules (5). The distribution of cells with I surface determinants has been studied in different organs of the chicken (6,7) Re
