Swelling-induced activation of large-conductance single-channel currents in on-cell patches. (A) Representative current traces recorded under isotonic and hypotonic conditions on C127i (top traces) and C127/CFTR (bottom traces) cells, during application of alternating pulses from 0 to ±25 mV (protocol is shown at the top of the traces). (B) Unitary i-V relationships recorded in cell-attached patches on C127i (open circles) and C127/CFTR cells (open triangles) as well as in inside-out patches excised from C127i cells (closed circles). The SEM values are shown by vertical bars where the values exceed the symbol size.
