Whole-Mount In Situ Hybridization (WISH) for Salamander Embryos and Larvae.

Whole-mount in situ hybridization (WISH) is widely used to visualize transcribed gene sequences (mRNA) in developing embryos, larvae, and other nucleotide probe permeable tissue samples. This methodology involves the hybridization of an antisense nucleotide probe to the target mRNA, followed by chromogen or fluorescence-based detection. Here we describe a protocol for the spatiotemporal analysis of mRNA transcripts in axolotl embryos/larvae using digoxigenin-labeled riboprobes, anti-digoxigenin alkaline phosphatase, Fab fragments antibody, and NBT/BCIP chromogen detection.
