Phallacidin is a natural bicyclic heptapeptide derived from the poisonous mushroom Amanita phalloides. Phallacidin binds to filamentous actin specifically with high affinity, with a Kd of 20 nM. After binding to F-actin, Phallacidin strongly inhibits its depolymerization, stabilizes microfilament structures, and prevents their disruption by drugs such as cytochalasins. When conjugated with a fluorophore, Phallacidin serves as a specific fluorescent probe for F-actin, which is used to clearly visualize the distribution of actin in the cytoskeleton (e.g., stress fibers, cortical peripheral bands) under fluorescence microscopy .

Biotin-11-dCTP is a biotinylated deoxynucleoside triphosphate and an important DNA labeling reagent. In random primer DNA labeling reactions, Biotin-11-dCTP incorporates into newly synthesized DNA strands to generate labeled DNA probes suitable for hybridization applications. In addition, Biotin-11-dCTP can serve as a substrate for terminal deoxynucleotidyl transferase to end-label oligonucleotides for telomere sequence detection, or to label the cut ends of linearized DNA molecules, thereby supporting streptavidin-based electron microscopy analysis. For example, Biotin-11-dCTP can label the cut ends of linearized DNA molecules under the action of dGTP and avian myeloblastosis virus reverse transcriptase .

Dehydroergosterol is a fluorescent cholesterol analog (Ex/Em = 325/375 nm) used in cholesterol transport, membrane structure research, and live-cell imaging. Unlike cholesterol, Dehydroergosterol contains three additional double bonds, an extra methyl group, and an ergosterol side chain, forming a conjugated system that produces intrinsic fluorescence. In its monomeric form, Dehydroergosterol exhibits excitation peaks at 310-311, 324, and 338-340 nm, as well as emission peaks at 354, 371-375, 390-394, and 414 nm; in its microcrystalline form, Dehydroergosterol shows enhanced excimer emission around 404 and 426 nm. Dehydroergosterol mimics the properties of cholesterol, integrates into membranes and lipoproteins, and localizes to organelles .

BODIPY 493/503 (solution) is a BODIPY dye. BODIPY dye is a small molecule dye with strong ultraviolet absorption ability, its fluorescence peak is relatively sharp, and the quantum yield is high. They are relatively insensitive to the polarity and pH of the environment and are relatively stable under different physiological conditions. Due to its structural asymmetry, BODIPY derives a variety of structural products. BODIPY lipid droplet dyes can well pass through the cell membrane into the cell, and localize the neutral lipids in the cell to specifically stain the lipid droplets, which can be used for labeling of live cells and fixed cells . Maximum excitation/emission wavelength: 493/503 nm.
Solvent and concentration: DMSO: 5 mM.
