Figure 2.

FACS measurement of ψ distinguishes CHO-Kv1.3 from CHO cells. Histograms of oxonol fluorescence in CHO (A, D), CHO-Kv1.3 (B, E) and a combination of CHO and CHO-Kv1.3 (C, F) untreated (gray lines) or treated (black lines) with MgTX (A, B, C) or IbTX (D, E, F). The ψ values in mV are depicted. Data are representative of four experiments.
