The kinetics of cell-mediated immunity to simian virus 40 (SV40) tumor-specific transplantation antigen (TSTA) were compared to the kinetics of tumor-unrelated parameters of immune responsiveness in the assessment of the immune statuses of inbred MHA/SsLAK hamsters during the course of progressive syngeneic SV40 tumor growth and after tumor excision.

Antiserum specific for hamster thymus-derived lymphocytes, prepared by immunization of rabbits with brain tissue from MHA/ssLAK hamsters, was, in the presence of guinea-pig complement, cytotoxic to hamster thymocytes greater than lymph node cells greater than spleen cells, while virtually unreactive against bone marrow cells. This antiserum markedely(More)
Dormant and developing embryos of Artemia salina contain equivalent amounts of eIF-2, the eukaryotic initiation factor which forms a ternary complex with GTP and Met-tRNAf. The factor was purified from 0.5 M NH4Cl ribosomal washes by (NH4)2SO4 fractionation, followed by chromatography on heparin-Sepharose, DEAE-cellulose, hydroxyapatite and(More)
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(More)
