The zebrafish is widely used for functional studies of vertebrate genes. It is accessible to manipulations during all stages of embryogenesis because the embryo develops externally and is optically transparent. However, functional studies conducted on the zebrafish have been generally limited to the earliest phase of activity of the gene of interest, which is a limitation in studies of genes that are expressed at various stages of embryonic development. It is therefore necessary to develop methods that allow for the modulation of gene activity during later stages of zebrafish development while leaving earlier functions intact. We have successfully electroporated the green fluorescent protein (GFP) reporter gene into the neural tube of the zebrafish embryo in a unidirectional or bilateral manner. This approach can be used for the functional analysis of the late role of developmental genes in the neural tube of zebrafish embryo and larvae.
