Cytotoxic Action of Normal Human Serum on Ehrlich Ascites and Sarcoma 180 Cells.

Abstract

(1) Thermolabile, non-dialyzable cytotoxins are present in normal, human serum for Ehrlich ascites and Sarcoma 180 cells. (2) Similarities and differences of these cytotoxins and those active against atypical human cell strains U12 and HeLa are described. (3) Data are presented showing relationship of these cytotoxins to serum complement.
