title: DNA synthesis inhibitory peptides in mammalian serum and insect hemolymph.
abstract: Similar inhibitory factors for DNA synthesis were found in fetal calf serum and a hemolymph of the moth, Bombyx mori. The factors were highly purified by gel filtration, ion exchange and thin layer chromatography and appeared to be heat-stable. They showed the same effects on some bacteria and mammalian cells. The significance of these DNA synthesis inhibitory 1 Kd peptides is discussed.
