[Topo-optical reactions on the membrane of the human red cell ghost (author's transl)].

Previous studies have proved that the thiazin dyes toluidine blue, azure A, azure B, 1.9-dimethyl methylene blue and the quinolin dyes N,N'-diethylpseudoisocyanine chloride, N,N'-6,6'-dichlorpseudoisocyanine chloride are suitable for topo-optical reaction on the membrane of the red blood cells. In the present study the applicability of the thiazin and quinolin dyes on the membrane of the human red cell ghost was examined. Optical analysis revealed that the thiazin dyes are bound in radial position to the membrane, while the quinolin dyes are bound parallel to the membrane's plane.
