Abstract

Immunohistochemistry is a widely used technique to examine the expression and subcellular localization of proteins. This technique relies on the specificity of antibodies and requires adequate penetration of antibodies into tissues. The latter is especially challenging for thick specimens, such as embryos and other whole-mount preparations. Here we describe an improved method of immunohistochemistry for retinal whole-mount preparations. We report that a cocktail of three reagents, Triton X-100, Tween-20, and DMSO, in blocking and antibody dilution buffers strongly enhances immunolabeling in whole-mount retinas from adult zebrafish. In addition, we establish that in whole retinal tissues, a classic epitope retrieval method, based on citrate buffer, is effective for immunolabeling membrane-associated proteins. Overall, this simple modification allows precise and reproducible immunolabeling of proteins in retinal whole-mounts.

Background

To understand complex biological processes, morphological and histological analyses allow for practical qualitative and quantitative approaches. Immunohistochemistry is a robust technique used to visualize the expression and localization of intra- and extra-cellular proteins. Although conventional histological sectioning offers high resolution images of immunostained proteins, sectioning 3-dimensional tissues results in poor preservation of tissue architecture. In sections, complete cellular structures and a complete understanding of the 3-dimentional distribution of proteins are not readily appreciated. In contrast, whole-mount preparations provide large volume 3D information, including intact cellular structures and the spatial relationships of cells and molecules in a complex tissue. However, adapting immunohistochemistry for use with intact tissues often results in poor permeability of antibodies, resulting in incomplete labeling, and a high degree of non-specific background.

In the retina, the cell body of the radial Müller glia spans the entire thickness of the retina (Bringmann et al., 2006). Microglia, the innate immune cells in the central nervous system, with a small cell body and ramified processes, are distributed throughout the retinal parenchyma (Li et al., 2015; Silverman and Wong, 2018). In response to neuronal damage or death, Müller glia and microglia undergo significant structural remodelling. Characterizing the morphology of these two cell types provides a readout the local environment surrounding each cell type and the overall health of the retina (Nagashima et al., 2020; Silva et al., 2020).

Detergents and organic solvents are common reagents that efficiently break down the permeability barriers of cells and nuclei (Jamur and Oliver, 2010). Triton X-100 and Tween-20 are widely used non-ionic detergents, which perturb the phospholipid bilayer structure of biological membranes (Kalipatnapu and Chattopadhyay, 2005; Koley and Bard, 2010; Cheng et al., 2019). Although dimethyl sulfoxide (DMSO), a polar organic solvent, or acetone, a common fixative,has been shown to enhance permeability of cell membranes (de Ménorval et al., 2012), its utility in immunohistochemical procedures is less common. Most procedures select a single reagent of detergents or solvents for permeabilization, and the efficiency of combining more than two chemicals is not well documented.

Here we describe an improved method of whole-mount immunohistochemistry. We report that a cocktail of three reagents, Triton X-100, Tween-20, and DMSO diluted in blocking and antibody dilution buffers dramatically enhances immunolabeling in whole-mount retinas. We also report that a classic citrate buffer based epitope retrieval method (Shi et al., 1993) is effective for immunolabeling membrane associate proteins. For completeness, we also include a detailed protocol for isolating whole retinas from zebrafish.
