Countercurrent distribution in a 2-phase polymer system of cultured cells following their exposure to trypsin, versen, dimethyl sulfoxide and suboptimal temperature

A study was made of the effects of trypsin (0.25%) EDTA (0.02%), DMSO (10%) and suboptimal temperatures (16-18 degrees C) on the line L cells of monolayer and suspension cultures by the method of counter-current distribution in two-phase polymer system Dextran-500/poly (ethylene) glycol-6000. It has been shown that these agents cause the increase in number of cells with low partition coefficient, which is most expressed in the population of monolayer subline cells.
