FIG. 2.

K⁺ release from Vero cells treated with rIb. Vero cells were incubated with rIb or the oligomer at 37°C. K⁺ concentrations in the medium were determined at given times by atomic absorption spectrometer. Symbols: •, Ib at 280 ng/ml; ▪, Ib at 56 ng/ml; ▴, Ib at 28 ng/ml; ○, Ib oligomer at 5.6 mg/ml; and □, without Ib (control)
