Abstract:

Biological fluids of mammalia possess a cancer-suppressive activity. CSF has been isolated from ascitic fluid (Ehrlich ascites carcinoma) in this laboratory. Chemically, it is a peptide complexing with lipids, and inhibits the cancer cells in vitro, but has a little effect on normal bone marrow cells. This paper reports the molecular homogeneity, amino acid composition, approximate molecular weight and terminal structures of the peptide.
