Abstract

Source: Icha J., et al. Using Light Sheet Fluorescence Microscopy to Image Zebrafish Eye Development. J. Vis. Exp. (2016).

This article describes sample preparation for light-sheet fluorescence microscopy. It also demonstrates a method to mount live zebrafish embryos for long term imaging, which allows recording of long time-lapse movies of live embryos in near-physiological conditions.

Protocol

1. Sample Preparation Preparing the Agarose Mix 15 min before making of the agarose mix, melt one 1 ml aliquot of 1% low melting point agarose (dissolved in E3 medium) in a heating block set to 70 °C. Once the agarose is completely molten, transfer 600 µl into a fresh 1.5 ml tube, add 250 µl of E3 medium, 50 µl of 0.4% MS-222 and 25 µl of vortexed bead stock solution. NOTE: This makes 925 µl of the mix, while additional 75 &#1…
