Source: Lara Al Hariri and Ahmed Basabrain at the University of Massachusetts Amherst, MA, USA Absorbance Wavelength ComparisonExpand In the first part of the lab, you'll use ultraviolet and visible light absorption spectroscopy, or UV-Vis absorption spectroscopy, to analyze the absorption characteristics of fluorescein, β-carotene, and indigo dye. To perform UV-Vis spectroscopy, you'll place a solution between a light source and a photodetector. The molecules will absorb light at...

Source: Lara Al Hariri at the University of Massachusetts Amherst, MA, USA Preparation of Dye SolutionsExpand Here, we show the laboratory preparation for 10 students working in pairs, with some excess. Please adjust quantities as needed. First, put on a lab coat, safety glasses, and nitrile gloves. Some solutions use hexane or dimethylformamide, so prepare those solutions in a fume hood. Prepare a 1 mM stock solution of fluorescein in water. Measure 0.0166 g of fluorescein...

FM Dyes in Vesicle Recycling
0 Views •
2023
FM dyes are a class of fluorescent molecules that has found important use in studying the vesicle recycling process. By virtue of a chemical structure, these molecules can insert themselves into the outer leaflet of phospholipid bilayer membranes. After membrane insertion, they are internalized into the cell via endocytosed vesicles, and released when these vesicles recycle back to the membrane. Since, these dyes fluoresce strongly in the hydrophobic environment within membranes and weakly in...

Source: Tamara M. Powers, Department of Chemistry, Texas A&M University Today's modern world requires the use of a large amount of energy. While we harness energy from fossil fuels such as coal and oil, these sources are nonrenewable and thus the supply is limited. To maintain our global lifestyle, we must extract energy from renewable sources. The most promising renewable source, in terms of abundance, is the sun, which provides us with more than enough solar energy to fully fuel our...

Here, we present a protocol to use pre-synthesized polymeric products derived from fungal laccase-catalyzed polymerization of plant phenols, either with or without mordant agents (e.g., FeSO4), to induce detergent-resistant keratin hair dyeing within 2.5 hours.
FAQs
The hydrocarbon chains embed in the lipid bilayer, creating a membrane anchor, while the fluorescent headgroup remains associated with that membrane. Because the dye can move laterally rather than readily crossing into the cytoplasm, fluorescence can follow continuous membrane surfaces. This makes membrane-linked routes visible in neuronal preparations.
Membrane association separates two functions of the molecule: the hydrocarbon portion retains the dye within the lipid environment, and the fluorescent portion supplies the detectable signal. This arrangement lets microscopy report the position and continuity of labeled membranes while preserving a distinction between membrane outlines and the surrounding cytoplasmic interior.
DiIC18(3) dye is especially informative when the question concerns structure connected through membranes. Its lateral movement can extend labeling along axons, dendrites, or other membrane-linked neuronal pathways, allowing investigators to examine how cellular form is organized across a neural route rather than viewing only an isolated labeled site.
At a conceptual level, labeling requires introducing the dye to membrane-containing neural material, permitting membrane association and lateral spread, and then examining the resulting fluorescence by microscopy. The observable outcome depends on retaining the membrane-linked signal during imaging, because the method is intended to reveal membrane architecture and neural pathways.
It can make axons, dendrites, and neural pathways visible, giving researchers information about neuronal morphology and anatomical connectivity. Because the signal follows membrane-associated structures, images can show how neuronal processes are arranged in relation to one another. These observations help connect cellular form with broader circuit structure.
Neuronal shape and pathway organization can change during development or after experimental injury and repair. By making membrane-associated architecture visible, DiIC18(3) dye supports comparisons of neuronal morphology, neural connections, and pathway organization across these contexts. The resulting anatomical information helps researchers relate structural patterns to developmental processes or repair-related changes.
