CD1D-deficient mice generate similar anti-RBC IgM alloantibody levels compared with WT mice in response to transfused stored RBCs. WT and CD1D-KO mice were transfused with stored HOD RBCs. Serum was collected 7 dpt and the levels of anti-HOD alloantibody generation were measured by (A) flow cross-match presented as adjusted MFI and (B) limiting dilution ELISA presented as IgM titer. Each dot represents one mouse. Bars on scatter plots represent median values. Figure shows a representative experiment out of 4. *p < .05, **p < .01, ***p < .001, ****p < .0001, ns p > .5. dpt, days post-transfusion; IgM, immunoglobulin M; ELISA, enzyme-linked immunosorbent assay; MFI, mean fluorescence intensity; WT, wild type
