We describe a protocol for transcardiac perfusion of mice, removal and sectioning of the brain, as well as immunoperoxidase staining, resin embedding, and ultrathin sectioning of the brain sections. Upon completion of these procedures, the immunostained material is ready for examination with transmission electron microscopy.

Endothelial corneal transplantation is a surgical technique for treatment of posterior corneal diseases. Mechanical microkeratome dissection to prepare tissue results in thinner, more symmetric grafts with less endothelial cell loss and improved outcomes. Dissections can be performed at the eye bank prior to corneal transplantation surgery.

Here, we present a detailed protocol to detect and quantify protein levels during craniofacial morphogenesis/pathogenesis by immunostaining using mouse craniofacial tissues as examples. In addition, we describe a method for preparation and cryosectioning of undecalcified hard tissues from young mice for immunostaining.

This protocol successfully prepared sufficient high-quality neovascular tissue from glioma samples using laser-capture microdissection for quantitative proteomics analysis of tumor angiogenesis, overcoming the limitations of studies that traditionally focus mainly on angiogenic factors and providing a large-scale proteomics profile of glioma angiogenesis.
FAQs
Fixation stabilizes tissue components before later processing, helping preserve the relationships among cells and surrounding structures. This matters because dehydration, embedding, and sectioning are intended to prepare the specimen without losing the architecture needed for interpretation. In practice, effective preservation lets microscopy reveal morphology as it existed in the biological sample, rather than only isolated or displaced features.
Dehydration removes water, embedding supplies support, and sectioning produces the thin slices required for microscopic examination. Their sequence connects processing with physical handling: the tissue must first be made stable and workable, then positioned in a supportive medium before it can be cut. Together, these steps expose internal organization while maintaining a usable specimen.
Stains increase visual contrast between cellular features, making boundaries and patterns easier to distinguish during microscopy. This added contrast complements structural preservation: preparation maintains the tissue’s arrangement, while staining helps the observer recognize components within that arrangement. As a result, researchers can examine morphology and tissue organization more clearly and compare features across normal or experimental samples.
Positioning determines how the preserved specimen is presented for sectioning and viewing. Consistent orientation helps microscopy capture tissue organization in a meaningful plane, which is important when researchers compare normal and experimental samples. By supporting a consistent presentation of structures, positioning improves the interpretability of morphological observations and complements the preservation achieved during earlier processing steps.
Comparable preparation makes differences in morphology and tissue organization easier to evaluate across normal and experimental samples. Fixation and processing preserve the structures being compared, while sectioning and staining make those structures visible under the microscope. This approach helps investigators distinguish patterns associated with an experimental condition from the baseline organization represented by the normal sample.
Prepared tissue sections support histology, developmental studies, disease investigation, and microscopy-based analysis of cellular organization. In histology, they provide a basis for examining tissue morphology; in developmental work, they allow organization to be viewed in biological samples; and in disease studies, they help investigators identify pathological changes. These uses connect microscopic structure with broader biological questions.
By producing thin, stained sections, tissue preparation makes cellular features and tissue organization accessible to microscopy. This allows researchers to inspect morphology in a form that presents internal structures more clearly than an unsectioned specimen. The outcome is especially useful when the goal is to identify pathological changes or assess how experimental samples differ from normal tissue.
