Abstract
The activity of the enzyme catalase was examined in 12 mammalian cell strains cultured for long intervals in vitro. Catalase activity of all cell strains was very low. Certain of the cultured cells were implanted into mice of the inbred strain from which the cells originated. The tumors arising from the implants, both of the sarcoma-producing strains and the one hepatoma-producing strain, had very low activity. The hepatoma-producing strain had much less activity than did spontaneous primary hepatomas excised directly from the mouse.Keywords
