A novel protein synthesized and isolated from mouse thymocytes is described. The protein can be separated from radiolabelled cell lysates by taking advantage of its insolubility in the cold. It is a macromolecule with a molecular weight of 225,000 daltons, migrates as a beta-globulin on electrophoresis and has unique antigenic determinents as shown by the production of a monospecific antiserum.
