Concentration dependence of uptake of polymers in MCF7-ADR cells expressed in % gated cells. Cells were incubated at 37 °C with solutions of different concentrations of fluorescently labeled diblock- (A) and triblock copolymers as well as EtOx homopolymer (both B). Incubation time 60 min. Concentrations of polymers are expressed as concentration of labeled polymers.

Experiments were performed in triplicate and data is expressed as means ± SEM. Data points were fitted with Boltzmann functions from which the EC50 values (concentration at 50 % gated cells) were calculated.
