Whole-Mount In Situ Hybridization

Whole-mount in situ hybridization (WMISH) is a common technique used for visualizing the location of expressed RNAs in embryos. In this process, synthetically produced RNA probes are first complementarily bound, or "hybridized," to the transcripts of target genes. Immunohistochemistry or fluorescence is then used to detect these RNA hybrids, revealing spatial and temporal patterns of gene expression. Unlike traditional in situ hybridization techniques, which require thin tissue sections whose...

Here, we describe a protocol for whole mount immunofluorescence and image-based quantitative volumetric analysis of early stage mouse embryos. We present this technique as a powerful approach to qualitatively and quantitatively assess cardiac structures during development, and propose that it may be widely adaptable to other organ systems.

The zebrafish embryo is an excellent model for developmental biology research. During embryogenesis, zebrafish develop with a yolk mass, which presents three-dimensional challenges for sample observation and analysis. This protocol describes how to create two-dimensional flat mount preparations of whole mount in situ (WISH) stained zebrafish embryo specimens.
FAQs
The support stabilizes the silk network while maintaining the web’s strand arrangement and tension. This is important because a cobweb has a delicate three-dimensional organization that can change when transferred or handled directly. By reducing distortion during preparation, the holder helps observations and documentation reflect the web’s original architecture more accurately.
Strand arrangement and tension provide structural information about how the web is organized in three dimensions. Preserving these features allows researchers to examine web architecture and silk organization rather than a preparation altered by handling. Consistent structural preservation also supports comparisons of morphology, construction patterns, and possible relationships between web design and ecological function.
Direct handling can be difficult because the web is a fragile biological material that is not easy to manipulate without disturbing its structure. Cobweb Holder Mounting provides stabilization during transfer, imaging, and handling, reducing structural distortion. This makes the preparation more suitable for microscopy-based examination and documentation than an unsupported web.
The preparation begins by securing the spider web on a support, followed by stabilizing the mounted silk network for transfer, imaging, or handling. The holder should preserve the strand arrangement and tension as much as possible, because these features are central to structural observation. The resulting preparation can then be documented or examined microscopically.
A mounted preparation can support examination of web architecture, silk organization, prey-capture structures, and species-specific construction patterns. Microscopy-based analysis and documentation make these features easier to observe while the network remains stabilized. Together, the observations can provide structural information for comparing webs and studying how spiders construct their silk networks.
The technique enables researchers to compare web morphology, investigate spider behavior, and relate structural features to ecological function. Preserving the web during observation is especially useful when the material is too delicate for easy direct manipulation. Mounted webs therefore connect a practical preparation step with broader studies of species differences, construction patterns, and biological function.
