The biarsenical dyes FlAsH and ReAsH bind specifically to tetracysteine motifs in proteins and can selectively label proteins in live cells. Recently this labeling strategy has been used to develop sensors for different protein conformations or oligomeric states. We describe the labeling approach and methods to quantitatively analyze binding.

Source: Elise S.D. Buki, Danielle N. Beatty, and Taylor D. Sparks, Department of Materials Science and Engineering, The University of Utah, Salt Lake City, UT The laser flash method (LFA) is a technique used to measure thermal diffusivity, a material specific property. Thermal diffusivity (α) is the ratio of how much heat is conducted relative to how much heat is stored in a material. It is related to thermal conductivity (), how much heat is transferred through a material due to a temperature...

Confocal scanning microscopy is applied for imaging single mitochondrial events in perfused heart or skeletal muscles in live animal. Real-time monitoring of single mitochondrial processes such as superoxide flashes and membrane potential fluctuations enables the evaluation of mitochondrial function in a physiologically relevant context and during pathological perturbations.
FAQs
The approach coordinates a brief illumination period or signal activation with rapid image acquisition. This timing restricts observation to a defined biological interval, helping distinguish changes that occur close together in time. Such synchronization is important when fluorescence, molecular location, or cell structure changes over milliseconds to seconds.
Rapid cellular events may begin and end before conventional imaging records enough frames to resolve them. Flash Reash Imaging focuses acquisition around the activated or illuminated interval, making transient changes more visible as time-resolved patterns. This can clarify the sequence of events underlying intracellular transport, signaling, or membrane remodeling.
The method can follow changes in fluorescence, molecular location, and cell structure. These readouts provide different views of a short-lived event: fluorescence can indicate a changing signal, molecular location can reveal redistribution, and structural imaging can show alterations in cellular form. Together, they support analysis of transient mechanisms rather than only final states.
Interpretation depends on relating each image to the biological event that triggered or accompanied it. When acquisition is precisely timed, researchers can compare molecular or structural changes with the event's progression over milliseconds to seconds. This relationship supports quantitative analysis and helps separate early, intermediate, and later features of a cellular response.
A typical workflow identifies the cellular event of interest, applies brief and precisely timed illumination or signal activation, and then collects images rapidly. Researchers can examine the resulting sequence for changes in fluorescence, molecular location, or cell structure. The final analysis links those image changes to the timing of the biological event.
The approach is suited to processes whose important features are temporary or rapidly changing. Supported examples include intracellular transport, signaling, membrane remodeling, and interactions between cells and their environments. In each case, time-resolved images can help reveal when cellular components move, signals change, or structures respond to surrounding conditions.
By connecting image acquisition with a defined activation or illumination event, researchers can observe how cells change as conditions shift. Measurements may show altered fluorescence, redistribution of molecules, or structural remodeling. These observations provide a time-dependent view of cellular responses and can help characterize mechanisms that would be obscured in a final-image comparison.
The resulting image sequences can provide quantitative information about transient cellular mechanisms. Researchers may assess the timing of fluorescence changes, molecular relocation, or structural alterations and relate those measurements to a specific biological event. This supports more precise characterization of dynamic processes than observations based only on static cellular states.
