Dynamics of the H₂O₂ levels during development. HyPer imaging in developing zebrafish embryos. The H₂O₂ levels are inferred from the YFP₅₀₀/YFP₄₂₀ excitation ratio of HyPer. (A) Blastula, (B-H) gastrulation. (E-H) During gastrulation, H₂O₂ is detected at the opposite side of the shield (E-H). (E, G) Bright-field images corresponding to F and H, respectively. (I) Early somitogenesis, (J) 20 somites (K) 30 hpf, (L) 48 hpf, (M) 72 hpf. Representative images are shown as lateral views, except for those in G-H (animal view). Pseudo-colour calibration bars: HyPer ratio (YFP₅₀₀/YFP₄₂₀). The bar common for A-H and the bar common for I-M allow the H₂O₂ levels in each group to be compared. Scale bars, 100 µm (A-J) and 200 µm (K-M). ot: optic tectum.
