Fluorescence recovery of Actin::GFP after photobleaching. Newly formed Actin::GFP foci in stage 14 embryos were photobleached (arrows) to approximately 30% of the original intensity. The recovery rate was recorded every 3s after photobleaching for a total of 165 sec (endpoint). A. Stills from time-lapse showing Actin::GFP recovery at an actin focus after photobleaching in wild-type and DMef2-Gal4> UAS-diaFH1FH2 embryos. Scale bar: 2.5μM B. Comparison of representative recovery kinetics of Actin::GFP foci in control (green) and DMef2-Gal4> UAS-diaFH1FH2 (red) myoblasts. C. Half time of fluorescent recovery in control (n = 8) and DMef2-Gal4>UAS-diaFH1FH2 embryos (n = 10). The half time of fluorescence recovery in DMef2-Gal4> UAS-diaFH1FH2 embryos (t1/2 = 17.7±6.7s) is significantly lower than control (t1/2 = 53.3±6.7s). D. Percentage of final recovery in control and DMef2-Gal4>UAS-diaFH1FH2 embryos. Final recovery in DMef2-Gal4> UAS-diaFH1FH2 embryos (77.9±10.6%) is similar to wild-type embryos (78.6±10.5%) (p>0.1).
