ChIn analysis. Compound transgenic zebrafish larvae expressing green fluorescent protein in neuromasts (arrowed in top panel) and dsRed in neutrophils. Upper panel shows recruitment of red fluorescent neutrophils to injured neuromasts in green. In the lower panel, the ChIn assay imaging scripts have identified the neuromasts (white boxes), and the amount of recruited red fluorescence (a measure of inflammation) can be assessed. Reproduced from Figure 5 in d'Alençon et al. .
