Expression of HCS-MiEx in Rohon-Beard neuron. Embryos were injected with the HCS-MiEx construct as described in methods. Two days later expression of the reporter was visualized in live embryos using a fluorescent microscope. Expressing embryos were photographed using a digital camera. The image shows a Rohon-Beard neuron. The cell body is overexposed to show the widely ramifying peripheral axon. Mag = 30×.
