Total Internal Reflection Fluorescence (TIRF) microscopy is a powerful approach to observe structures close to the cell surface at high contrast and temporal resolution. We demonstrate how TIRF can be employed to study protein dynamics at the cortex of cell wall-enclosed bacterial and fungal cells.

In this video, we describe the interference reflection microscopy (IRM) technique to visualize microtubules growing on a coverslip surface in the presence of a suitable buffer. Upon illumination with incident light, the coverslip-buffer interface and buffer-microtubule interface reflect light, which combines to create an interference pattern, enabling the visualization of microtubules as high-contrast images against a bright background.
FAQs
Visual Molecular Dynamics maps atom coordinates from structural data into an interactive three-dimensional display while representing relationships such as bonds. This coordinate-based view lets users inspect spatial arrangement rather than relying only on textual or numerical records. Because the graphics can be examined interactively, researchers can connect molecular geometry with the visible organization of a protein, nucleic acid, membrane, or complex.
A trajectory adds a time dimension to the coordinate display, allowing Visual Molecular Dynamics users to compare molecular arrangements across successive points in a simulation. Examining those changes can reveal conformational shifts and help researchers evaluate whether the simulated system behaves consistently over time. This temporal perspective is especially useful when a static structure cannot show how biomolecular shape changes.
Geometry and distance analyses translate visual inspection into more explicit structural observations. Researchers can examine molecular geometry, measure distances between relevant atoms or regions, and relate those results to observed dynamics. In biochemistry, this combination helps connect a changing three-dimensional arrangement with questions about protein structure, nucleic-acid organization, membranes, or protein-ligand interactions.
A practical workflow begins with structural data, followed by interactive inspection of atom and bond representations. Researchers can then examine coordinates, apply analyses of geometry, distances, or dynamics, and compare what they observe with the behavior of the molecular system. This progression moves from structural visualization to targeted interpretation without separating the graphical view from the measurements.
It is particularly useful for studying proteins, nucleic acids, membranes, and protein-ligand interactions, where spatial relationships and movement influence interpretation. Researchers can investigate conformational changes and simulation behavior through structural observations. The software is valuable when biochemical conclusions depend on molecular features that are difficult to infer from a single static structure, linking computational results with molecular mechanisms.
The results may include recognition of conformational changes, evaluation of simulation behavior, and measurements of molecular geometry or distances. Researchers can also produce publication-quality images that present these observations clearly. Together, these outcomes support interpretation of computational experiments and help communicate molecular mechanisms that are difficult to convey through static structural information alone.
