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.

The branchial skeleton, including gill rakers, pharyngeal teeth, and branchial bones, serves as the primary site of food processing in most fish. Here we describe a protocol to dissect and flat-mount this internal skeleton in threespine sticklebacks. This method is also applicable to a variety of other fish species.
FAQs
Glycerol helps limit dehydration while bringing the specimen’s refractive properties closer to those of the surrounding medium. This combination can reduce optical mismatch and support clearer visualization through the mounted sample. For neuroscience preparations, the benefit is especially relevant when examining fine neural structures, where improved optical clarity can make cellular organization and neuroanatomical detail easier to observe.
Glycerol can help maintain fluorescence in labeled tissue while supporting clear optical imaging. That property is useful after histological or immunofluorescent staining, when researchers need to examine signals such as synaptic markers alongside tissue structure. Preserving the quality of those signals can support more dependable interpretation of labeled neural features during microscopy.
Beyond image formation, proper mounting helps protect the prepared sample during imaging and storage. This protection supports more reliable observations when researchers examine the specimen after staining. In neuroscience, that stability is valuable for studying cellular organization and neuroanatomical detail in fixed tissue preparations without treating mounting as a separate concern from image quality.
After a neural specimen has been fixed and stained, it is placed in a glycerol-based medium on a slide and covered with a coverslip. The tissue remains between the slide and coverslip while the medium surrounds it. This arrangement provides the optical and protective setting needed for microscopy and subsequent storage of the preparation.
The technique can support microscopy of fixed brain sections, individual neurons, axons, and tissue containing labeled synaptic markers. It is therefore relevant to preparations produced by histological or immunofluorescent staining. Choosing this mounting approach allows researchers to examine both broader neuroanatomical organization and selected cellular or molecular features within the prepared neural tissue.
These preparations can support observations of cellular organization, axonal structure, and broader neuroanatomical detail. When fluorescent labels or synaptic markers are present, microscopy can also reveal the distribution of those signals within fixed tissue. Clearer imaging and sample protection together can produce more reliable visual evidence for interpreting stained neural structures.
