Abstract
We describe the production and some of the properties of a monoclonal antibody which inhibits binding of Interleukin 2 (IL-2) to rat T lymphoblasts as well as the capacity of these lymphoblasts to proliferate in response to IL-2 of rat or murine origin. According to these criteria, the antibody seems to be directed against an antigenic determinant on the IL-2 receptor. The antibody, obtained from hybridomas derived from mice immunized with phorbol-myristate-acetate-pulsed rat T lymphoblasts, exhibited species specificity, indicating that IL-2 receptors of various species are not necessarily identical, even if they can respond to IL-2 from different species.
