ABSTRACT:
A method of preparing an analog of bacteriorhodopsin in which organic cations selectively replace calcium and magnesium cations. The method comprises preparing a cation-free blue membrane and incubating the blue membrane with an organic cation selected from the group consisting of monovalent quaternary ammonium cations, bolaform cations and pyridinal cations.
