title: Antigen binding and capping by lymphocytes of genetic nonresponder mice.
abstract: Radioautographic study of the binding of GAT-(125)I to spleen cells of genetic responder and nonresponder mice demonstrates that among mice not injected with antigen all strains have approximately the same number of antigen-binding cells; after injection with antigen the number of antigen-binding cells increases in responders but not in nonresponders. Nonresponders are shown to make antibody after injection with GAT complexed with an immunogenic carrier, demonstrating the presence of potentially functional B cells in responders and nonresponders alike. When incubated in the warm, antigen-binding cells of both responders and nonresponders concentrate antigen at one pole of the cell, forming caps.
