Abstract
A substantially pure species of avian Interleukin-2 has a molecular weight of about 30 kda. as determined by SDS-polyacrylamide gel electrophoresis. The compound is obtained from avian lymphocytes. It is produced by collecting lymphocytes from an avian donor, growing the lymphocytes in a medium containing a T cell mitogenic agent, and recovering the compound from the medium.
