Abstract

Whole-mount in situ hybridization (WISH) and whole-mount immunohistochemistry (WIHC) are informative methods commonly used to analyze the spatiotemporal and quantitative distribution of mRNAs and proteins. However, these methods require multiple buffer changes and the imposition of time- and nerve-consuming efforts. To facilitate the whole-mount analyses, we innovated an easy and one-step buffer exchange system named "InSitu Chip" based on a single column containing two attached filters. This system improves the speed and stabilizes the different steps of the currently available protocols, providing fast and uniform operations. The InSitu Chip system is especially appropriate for multicolor whole-mount analyses using fluorescent detection. Furthermore, the InSitu Chip system is also suitable for large-scale whole-mount experiments associated with genome, transcriptome, and/or proteome analyses requiring high-throughput, high-quality, and reproducible results. Using the InSitu Chip, about 1,500 gene expression patterns were stably surveyed in ascidian Ciona intestinalis juveniles.
