N2 - Neuraminidase-sensitive negative charge sites on sheep red blood cells (SRBCs) are uniformly distributed over the cell surface, as in other species. Unlike most other species in which charge sites are immobile, however, in intact RBCs interaction of SRBCs with cationized ferritin (CF) induces clustering (i.e. patching) of CF-binding sites. This clustering is both time- and temperature-dependent. The clustering of negative charge sites results in the formation of domains up to 1 000 Å across which are totally free of CF binding sites. The unusually high degree of lateral mobility of ionogenic groups at the SRBC surface may contribute to the species specificity of E rosetting.
