Induction of hamster T cell-specific antiserum in rabbits using hamster brain tissue.

Antiserum specific for hamster thymus-derived lymphocytes, prepared by immunizing rabbits with hamster brain tissue, was cytotoxic to hamster thymocytes greater than lymph node cells greater than spleen cells, while virtually non-reactive against bone marrow. This antiserum inhibited spleen cell response to the T cell mitogen, phytohemagglutinin, but not to lipopolysaccharide, a B cell mitogen.
