Abstract
Summary
Material obtained from sonically disrupted HeLa cells by extraction of trichloracetic-acid precipitate with buffered saline was used to sensitize tanned sheep erythrocytes. Sensitized erythrocytes were agglutinated to high titer by anti-HeLa rabbit serum, but minimally by normal rabbit serum. Reactivity of the sensitizing extract was considerably reduced by treatment of HeLa cells with tannic, acid prior to disruption and extraction.
