Porin activity of native Tromp1. FPLC-purified native Tromp1 was added to the aqueous-phase (1 M KCl) bathing a lipid bilayer membrane. Histogram of single-channel conductance increases for over 136 membrane insertion events. Conductance increases showed a mean distribution ca. 0.96 ± 0.33 nS (± the standard deviation).
