Immunohistochemistry is a powerful lab technique for evaluating protein localization and expression within tissues. Current semi-automated methods for quantitation introduce subjectivity and often create irreproducible results. Herein, we describe methods for multiplexed immunohistochemistry and objective quantitation of protein expression and co-localization using multispectral imaging.

Source: Lauer, S. M., et al. Visualization of Cortical Modules in Flattened Mammalian Cortices. J. Vis. Exp. (2018) This video demonstrates a method to visualize the cortical modules in flattened brain sections using histochemical staining. Pre-fixed sections are treated with a straining reagent that highlights active neural clusters, forming dark, high-contrast regions. After mounting and dehydration, cortical modules appear under a bright-field microscope as dark, patchy patterns.

DiRita1 1 Department of Microbiology and Molecular Genetics, Michigan State University, East Lansing, Michigan, United States of America Bacteria are diverse microorganisms found nearly everywhere on Earth. Many properties help distinguish them from each other, including but not limited to Gram-staining type, shape and arrangement, production of capsule, and formation of spores. To observe these properties, one...

The reagent interacts with a target chemical component in a particular cellular or tissue location. This interaction produces a visible color difference, allowing the target’s distribution to be compared with surrounding structures under a light microscope. Because different reagents reveal different substances, the resulting pattern connects microscopic appearance with tissue composition and organization.
Each method is selected for its ability to react with or bind to a particular class of substance or biological activity. Consequently, one stain may emphasize a chemical component while another highlights enzyme activity or a different structural feature. Using distinct reactions helps researchers examine several aspects of the same specimen rather than relying on morphology alone.
Visibility depends on the condition of the collected specimen, how it is prepared, the chemical reagent applied, and the resulting color contrast. These steps determine whether a target remains available for reaction and whether its location can be distinguished microscopically. Careful preparation therefore supports reliable interpretation of cellular and tissue patterns.
A typical workflow begins with specimen collection and preparation, followed by application of a dye or reactive reagent suited to the substance being examined. The treated specimen is then viewed by light microscopy, where localized color differences are assessed. This sequence links chemical detection to the tissue’s microscopic structure and permits comparison among regions or tissue types.
Researchers may use it to investigate normal anatomy, follow developmental changes, examine disease-related alterations, or evaluate how tissues respond to experimental conditions. The method is especially useful when the question concerns where a substance or activity occurs within a tissue. Its spatial information connects cellular composition with broader biological changes.
Patterns of localized color can reveal differences in chemical composition between cells, regions, or tissue types. Examining these patterns alongside microscopic structure helps researchers assess cellular organization and identify changes associated with development, disease, or experimental treatment. The outcome is therefore both compositional and spatial, rather than a simple indication that a specimen contains a substance.
