Source: Etienne, F. et al. Two-photon Imaging of Microglial Processes' Attraction Toward ATP or Serotonin in Acute Brain Slices. J. Vis. Exp. (2019)This video demonstrates the use of two-photon microscopy to study the attraction of microglial processes toward an injected compound in brain slices. It provides an overview of preparing mouse brain slices, injecting a chemoattractant test compound, and imaging fluorescently labeled microglia to visualize their responses.

Source: Kay Stewart, RVT, RLATG, CMAR; Valerie A. Schroeder, RVT, RLATG. University of Notre Dame, IN Compound administration is often an integral component of an animal study. Many factors need to be evaluated to ensure that the compound is delivered correctly. The route of administration affects the mechanisms of absorption. The characteristics of the substance to be introduced (the pH, viscosity, and concentration) may dictate which route of administration is selected.

Atoms and Molecules Everything in the universe is made up of matter, and matter is composed of a combination of elements. An atom is the smallest unit of an element that retains all properties of the element. For example, a silver coin is made up of silver atoms, and each silver atom retains the unique properties of the element — silver. Elements are pure substances consisting of identical atoms that cannot be broken down into simpler substances by chemical changes. Atomic elements contain...
FAQs
The objective lens first forms an intermediate image of the specimen, and the eyepiece then enlarges that image for observation. This two-stage arrangement allows analysis at high magnification rather than relying on a single lens. The resulting view supports examination of cellular details, tissue organization, microorganisms, and other biological structures.
These conditions determine how clearly structures can be distinguished. Illumination provides the light needed to view the specimen, focus brings selected details into a sharp view, and staining improves contrast between structures. Together, they can make cellular features more visible, allowing observations of size, shape, organization, or changes to be interpreted more consistently.
Analysis becomes informative when visible features are examined systematically rather than viewed alone. Investigators can compare specimen size, shape, organization, abundance, or visible changes across samples. These comparisons help connect microscopic appearance with biological questions, such as whether samples contain different structures or show altered cellular or tissue characteristics.
A useful examination depends on selecting suitable illumination, bringing the relevant structures into focus, and using staining when additional contrast is needed. These factors affect which details are visible in the observed image. Consistent attention to them improves comparisons among samples and helps ensure that apparent differences reflect specimen features rather than unclear viewing conditions.
This approach is useful when biological investigations require direct examination of cells, tissues, microorganisms, or other visible structures. Its applications include cell identification, microbiology, histology, disease research, and laboratory studies of biological structure and function. The method is especially relevant when researchers need to compare organization or visible changes among samples.
Observations can support identification of cells or microorganisms and reveal how structures are arranged within a specimen. Analysis may also show differences in size, shape, abundance, or visible condition between samples. In biology, these outcomes provide evidence for studying tissue characteristics, disease-related changes, and relationships between biological structure and function.
