Anti-ephrinA5 antibody specificity. EphrinA5 protein expression is represented on sagittal parietal cortex sections of wild type (wt) and ephrinA5 KO (eA5KO) mice. EphrinA5 was strongly expressed particularly in the parietal cortex of wild type mice at E16.5, whereas no staining was observed in the brain of eA5KO mice. Scale bar: 75 μm. Abbreviations: see list.
