(A) Representative current traces (from > 30 independent experiments) that demonstrate asymmetry of the pore formed by NTHi P5, purified with OG P5, and incorporated into planar bilayers of DiPhPC between symmetric solutions of 1 M KCl, 10 mM Tris, pH 7.3 at 22°C. (B) I/V relationship of OG-P5 in panel A.
