This video demonstrates procedures for characterization of human pancreatic islets using hematoxylin and eosin (H&E) and immunohistochemistry (IHC). Pancreatic sections from head, body, and tail regions are stained by both H&E and IHC to determine islet endocrine composition (insulin, glucagon, and pancreatic polypeptide), cell replication (Ki67), and inflammatory infiltrates (H&E, CD3). The uncinate region is localized using IHC for pancreatic polypeptide.

A simplified yet accurate method to collect and stain mosquito hemocytes is described. Our method combines the simplicity of perfusion with the accuracy of high injection techniques to isolate clean preparations of hemocytes in Aedes mosquitoes. This method facilitates studies requiring knowledge of the types of hemocytes and their abundance.

Optimized Negative Staining: a High-throughput Protocol for Examining Small and Asymmetric Protein Structure by Electron Microscopy

More than half of proteins are small proteins (molecular mass <200 kDa) that are challenging for both electron microscope imaging and three-dimensional reconstructions. Optimized negative staining is a robust and high-throughput protocol to obtain high contrast and relatively high resolution (~1 nm) images of small asymmetric proteins or complexes under different physiological conditions.

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...

Small-animal positron emission tomography enables the assessment of the brain's two main energy substrates: glucose and ketones. In the present method, 11C-acetoacetate and 18F-fluorodeoxyglucose are injected sequentially in each animal, and their uptake is measured quantitatively in specific brain regions determined from the magnetic resonance images.
FAQs
Complementary staining increases interpretive value by assigning different visual signals to distinct targets in one specimen. When the stains bind selectively or create contrasting colors, researchers can compare cellular or tissue features without losing their shared spatial relationship. This helps distinguish coexisting components and assess complex biological arrangements more effectively than a single signal.
Selective binding allows each stain to highlight a different cellular structure, organism, or tissue component, while contrasting colors make those targets easier to distinguish during microscopic examination. Together, these properties reduce ambiguity when multiple features occupy the same sample. The resulting visual separation supports comparisons that would be difficult if both targets produced indistinguishable signals.
A single stain can emphasize one target or visual characteristic, whereas dual staining provides a paired view of two distinguishable features in the same biological context. This comparison can reveal relationships between components, improve cell or tissue characterization, and support interpretation of interactions. Its advantage comes from complementary information rather than simply increasing the amount of color.
A typical workflow includes preparing the biological sample, applying the two stains in sequence, using fixation as part of sample processing, washing when required, and examining the result microscopically. The exact order depends on the targets and stains selected. Coordinating these steps is essential for retaining distinct signals and allowing both features to be compared within one specimen.
The stains should provide distinguishable signals and correspond to the features being investigated. Their usefulness depends on whether they bind selectively to different targets or produce clearly contrasting colors during microscopy. A suitable pairing allows researchers to identify cellular or tissue components separately while preserving the shared spatial context needed for comparison and interpretation.
Researchers can apply this approach to cell identification, tissue characterization, viability assessment, and analysis of interactions between biological components. It is especially useful when a specimen contains several features that must be interpreted together rather than separately. By combining complementary signals, the method can provide a broader view of specimen organization and biological relationships.
