Figure 2. Relative to guide RNA rhosg3, rhosg1 causes greater reductions in rod opsin and greater rod photoreceptor loss. 6 ng of Cas9 mRNA and 2 ng of sgRNA were co-injected. (A) Rod opsin levels assayed in individual eyes by dot blot assay at 14 dpf. Each data point represents a different animal. P values are for Tukey multiple comparisons test for comparisons with WT group. P (ANOVA) = 2.9 × 10−9 (B) Phenotypes assessed by confocal microscopy. Green: anti-rhodopsin (B630N). Red: wheat germ agglutinin. Blue: Hoechst 33342. RPE: retinal pigment epithelium. OS: outer segments. IS: inner segments. ONL: outer nuclear layer. INL: inner nuclear layer. Bar = 50 µm.
