Staining for erythrocyte rosetting receptors varies with Dantu genotype. The relative expression of putative erythrocyte rosetting receptors was measured using monoclonal antibody Fab fragments and Alexa Fluor 488–conjugated secondary antibodies in flow cytometry. Seven non-Dantu, seven Dantu heterozygous, and seven Dantu homozygous samples were tested. Statistical comparison across groups was performed by one-way analysis of variance with Dunnett’s multiple comparisons test. Statistically significant differences were observed for glycophorin A (A) (non-Dantu versus Dantu homozygous, *P < 0.05), band 3 (B) (non-Dantu versus Dantu heterozygous, ***P <0.001; non-Dantu versus Dantu homozygous, ****P <0.0001), and complement receptor 1 (CR1) (E) (non-Dantu versus Dantu heterozygous, *P <0.05), but not for Wrightb (C) (P = 0.5572) or glycophorin C (D) (P = 0.4472). Bars show the mean and standard error of the mean for each genotype.
