Flow cytometry sorting of fluorescent cone photoreceptors for gene expression analysis. (a and b) FACS plots for transgenic Tg(TαCP:EGFP) embryos that are wild type at the pde6c+/+ locus showing the side scatter (SSC) and EGFP profiles. (c and d) FACS plots for mutant Tg(TαCP:EGFP)-pde6cw59/ cone photoreceptors. (e) Quantification of real-time RT-PCR expression data for rip1 and rip3 from EGFP-positive cells at 4 and 7d.p.f. in photoreceptors from wild-type (wt) and mutant (mt) embryos. Data presented as meanĀ±S.E.M. *P<0.05, n=9. (f) Relative RT-PCR analysis for rod photoreceptor genes (pde6a, pde6c, rho), cone pde6h gamma subunit and β-actin internal control from whole adult retinal RNA (lanes 1 and 6); FACS-sorted mutant cone RNA (lanes 2 and 4); FACS-sorted wild-type cone RNA (lanes 3 and 5).
