Abstract
The length of time mice were able to show a secondary cell-mediated response after a tumor allograft was investigated. C57B1/6 mice were inoculated ip with P-815 mastocytoma cells and, at selected time intervals up to 12 months after immunization, spleen cells were placed in JLC in an attempt to generate secondary CTL activity. It was found, as measured by the 51Cr-release assay, that all mice tested had significant secondary CTL activity 3 months after allograft. The ability to generate a secondary response then decreased with considerable individual variation up to 6 months post-immunization. No significant difference in CTL activity was found between immunized and age-matched control mice 12 months after tumor allograft.
