- •
Melittin channel exhibits ohmic behavior in a mercury-supported tethered BLM.
- •
Ohmic behavior requires a pretreatment of electrochemical impedance spectroscopy.
- •
Ohmic behavior also requires a relatively high melittin concentration, e.g. 0.8 μg/mL.
- •
Ohmic behavior is explained by persistent melittin channel transmembrane orientation.
