title: Stability studies on horse antithymocyte globulin.
abstract: Two equine antithymocyte globulin preparations were studied with respect to their relative rosette inhibition activity after storage at 4 and 25 C. After storage at 4 C for 48 months no activity loss was observed; 25 C storage resulted in fragmentation and eventual loss of relative rosette inhibition activity. A third preparation was studied by monkey skin graft prolongation. During a 1-year period, there was no loss of immunosuppressive activity as measured by this method and the rosette inhibition assay.
