[Inverse binding of lectin to either area of the plasmalemma of the enucleating normoblast (author's transl)].

The study was concerned with properties of either area of the cell membrane of the enucleating erythroblast, i.e. the plasmalemma envelope of the nucleus under extrusion and the future membrane of the reticulocyte. The findings did not corroborate the notion of a decline of the negative surplus charge of the plasmalemmal envelope. At this area of the erythroblast membrane it was demonstrated an increased lectin binding associated with the loss of toluidine blue induced anisotropy.
