Figure 7.
Pulse-induced molecular uptake of YP1 from control medium (2 µM YP1 in RPMI-1640) and from the pre-adsorbed YP1 solution after 5-minute incubation with U-937 cells. The amount of YP1 available for pulse-induced uptake is reduced by about 50% in the medium pre-incubated with U-937 cells. Data are from three separate experiments with 17–18 cells in each experiment.
