Gene editing technologies have enabled researchers to generate zebrafish mutants to investigate gene function with relative ease. Here, we provide a guide to perform parallel embryo genotyping and quantification of in situ hybridization signals in zebrafish. This unbiased approach provides greater accuracy in phenotypical analyses based on in situ hybridization.

Immunostaining is an effective technique for visualizing specific cell types and proteins within tissues. By utilizing sonication, the protocol described here alleviates the need to dissect Drosophila melanogaster tissues from late-stage embryos and larvae before immunostaining. We provide an efficient methodology for the immunostaining of formaldehyde-fixed whole mount larvae.

Drosophila oogenesis continues to be exceptionally useful in the study of mitochondrial proliferation and inheritance. This manuscript describes a detailed protocol used to label the replicating mitochondrial DNA (mtDNA) in Drosophila adult ovaries with 5-ethynyl-2´-deoxyuridine (EdU), which facilitates uncovering mechanisms associated with mitochondrial inheritance that were previously debatable.

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...
FAQs
Signal specificity begins when a labeled antibody or molecular probe binds selectively to its matching target. Depending on the experiment, that target may be an antigen, protein, nucleic acid, or microbial component. The attached enzymatic or fluorescent label then generates a visible signal, allowing microscopy to associate the target with its precise location in the specimen.
Maintaining the specimen’s organization shows where targets occur relative to surrounding cells and tissue structures. This spatial context can distinguish pathogen locations, immune cell distributions, and patterns of antigen presence that would be difficult to interpret from target detection alone. In infection studies, it also helps connect cellular responses with the organization of host-pathogen interactions.
Both label types create visible signals after selective binding, but they require appropriate microscopy for detection. Fluorescent labels provide a signal associated with fluorescence-based observation, whereas enzymatic labels generate a visible reaction product. The selected label therefore influences how the stained specimen is examined and how target distribution is visualized within the sample.
The choice of binding reagent determines which feature becomes visible. Labeled antibodies can detect specific antigens or proteins, while molecular probes can identify nucleic acids or microbial components. This range allows the same general staining approach to address different questions, including whether a target is present, which cells contain it, and how it is distributed.
A typical workflow begins with a prepared tissue, cell culture, or other biological specimen. Researchers apply a labeled antibody or molecular probe selected for the target of interest, allow selective binding to identify that target, and examine the specimen with appropriate microscopy. The resulting signal is interpreted in relation to the preserved spatial organization of the sample.
The technique is useful when researchers need to connect molecular detection with tissue location. It can show where pathogens reside, identify immune cell populations, map antigen distribution, and relate cellular responses to tissue organization. These observations provide spatial evidence for studying disease mechanisms and host-pathogen interactions rather than considering target signals independently of their biological setting.
