INTERFERON AND CELL DIVISION, I. INHIBITION OF THE MULTIPLICATION OF MOUSE LEUKEMIA L 1210 CELLS <i>In Vitro</i> BY INTERFERON PREPARATIONS

Abstract

Mouse interferon preparations inhibited the multiplication of mouse leukemia L 1210 cells in stationary suspension cultures. The degree of inhibition was found to correlate with the antiviral titer of the interferon preparations. The factor(s) responsible for inhibition of L 1210 cell multiplication could not be dissociated from interferon by standard physicochemical means.
