Fig. 6. Flat-mount in situ hybridization of E7.5 chick retinas electroporated with EnRaxLHD alone (A-C), EnRaxLHD plus RaxL (D-G), EnRaxLHD plus Rax (H-K) or EnRaxLHD plus mouse Crx (L-N) viral constructs. The sections of the retina samples in F,J are shown in G,K, respectively. The signals of endogenous visinin transcripts are shown in purple, EnRaxLHD viral transcript is shown in green-blue, and 3C2 mAb, which stains all viral infected patches, is shown in brown. The arrows in D,E indicate the visinin expression is partially rescued by RaxL. Scale bars: in A, 2 mm for A-F,H-N; in G, 30 mm for G,K.
