Protein levels of retinal photoreceptor in copper stressed embryos. A Immunostaining of Rodopsin (labeling retinal rod cells) (A1-A9). B Double immunostaining of ZPR-1 (labeling retinal cone cells) and Opn1sw2 (blue opsin, labeling retinal rod cells) in embryos at 10 dpf. A10, B13, B14, Quantification of protein level in each sample. Scale bars: A1-A9 and B1-B12, 50 μm; **, P < 0.01; *, P < 0.05
