We report a simplified and reliable method for non-radioactive in situ hybridization to whole Drosophila embryos. In the previous method (Tautz and Pfeifle, 1989) the post-hybridization wash, or the procedure for washing non-hybridized probe away from embryos depends simply on diffusion. We modified the method with application of electrophoresis to the wash. After hybridized with RNA probe, embryos were transferred to a small well where an electric charge was given to drive non-hybridized probe away from the embryos. This procedure enables us to acquire a much higher signal-to-noise ratio than that obtained from a conventional method. Furthermore, this is a time-saving method. We propose a term "electro-wash" for this procedure. 相似文献
