| abstractText | Whole-mount in situ hybridization (WISH) is a useful method for detecting specific gene expression patterns at their site of action during embryonic development. Traditional WISH methods are costly and suitable only for mouse embryos younger than 11.5 days. We present here an economical and practical in situ hybridization method using DIG-labeled RNA probes. We changed the conditions in several steps to make the WISH method suitable for whole mouse embryos from embryonic days 9.5 to 12.5 and for older stage mouse embryonic organs. We performed all steps in one microcentrifuge tube up to the staining steps to avoid losing or damaging the mouse embryos. We re-used the solutions and materials to make the method more economical and suitable for less sophisticated laboratories. We also performed beta-galactosidase staining on Tb x 18 Cre/Rosa26/LacZ mouse embryos; the results agreed with the in situ hybridization results. Finally, we sectioned the specimens after hybridization and beta-galactosidase staining; the results agreed with the literature. |
