Specificity of ion channel inhibitors for the maxi cation channel in rye root plasma membranes

Abstract

The pharmacology of the maxi cation channel in the plasma membrane of rye (Secale cereale L.) root cells was studied following its incorporation into planar lipid bilayers. The channel was inhibited by ruthenium red, diltiazem, verapamil, and quinine at micromolar concentrations and TEA+ at millimolar concentrations.
