Fig. 7. R cells are not depleted of ATP. (A) The average luminance and s.e.m., per retina, as determined using luciferin/luciferase-based ATP assays performed on retinas taken from wild-type (gray) or SdhA¹¹¹⁰ mutant mosaic (blue) flies at 0 and 5 days after eclosion. (B-I) Cross sections of the laminas (B,C,F,G) or retinas (D,E,H,I) from animals raised in complete darkness. Laminas are stained with the R cell-specific antibody mAb24B10 (green) and CSP (magenta). (B,D,F,H) Wild type. (C,E,G,I) SdhA¹¹¹⁰ mutant. (B-E) 0 days after eclosion. (F-I) 5 days after eclosion.
