5-ROX (5-Carboxy-X-rhodamine), a rhodamine dye, exhibits strong fluorescence in aqueous buffer with an excitation wavelength (λexit) of 580 nm (ε = 3.6×10^4 (M·cm)) and an emission wavelength (λemit) of 604 nm (ϕ = 0.94).

8-(4-ethynylphenyl)-1,3,5,7-tetramethyl BODIPY is an organic fluorescent dye characterized by an ethynylphenyl group at the 8-position of the boron dipyrromethene (BODIPY) structure and methyl substituents at the 1, 3, 5, and 7 positions. It boasts a high fluorescence quantum yield and specific chemical properties, making it useful for applications such as fluorescence imaging.

8-(4-bromophenyl)-1,3,5,7-tetramethyl-BODIPY is a derivative based on the BODIPY structure, featuring four methyl groups at positions 1, 3, 5, and 7, with a para-bromophenyl group attached at position 8. This compound finds extensive use in fields such as bioimaging, chemical analysis, and materials science, serving as a fluorescent probe for imaging biological samples, detecting specific chemicals, or in the development of optical materials.

FD&C Yellow No. 5 Aluminum Lake is a synthetic lemon yellow azo dye primarily used as a food coloring.

bis-ANS is a high-affinity non-covalent extrinsic fluorescent dye used to analyze protein conformation.[1] Its predominant interaction with proteins is through its hydrophobic phenyl and naphthyl rings.[2] bis-ANS has an excitation maxima of 390 nm.[3] It has an emission maximum of 523 nm when free in solution but undergoes a blue shift with an increase in fluorescence intensity when bound to protein; for example, when bound to intestinal fatty acid binding protein (FAPB2) it has emission maxima of 484-496 nm. bis-ANS has been used to label mechanically damaged neurons in acute brain slices.4 It also potently inhibits microtubule assembly.[5],[6]

Biotin-11-dUTP [tetra(triethylammonium) salt] [(2S,3S,4R,5R,6R)-5-(2,4-dioxopyrimidin-1-yl)-4-hydroxy-6-(hydroxymethyl)-2-[(3aR,4S,6R,6aS)-2-oxohexahydro-2H-thieno[3,4-d]imidazol-4-yl]-tetrahydro-2H-furo[3,2-d][1,3,2]dioxaphosphorin-3-yl]phosphonate] is used as a fluorescent substitute for dTTP.

Z-Gly-Pro-Arg-4MβNA is a thrombin substrate that, when cleaved by thrombin, releases 4-methoxy-2-naphthylamine (4MβNA). The liberated 4MβNA reacts with 5-nitrosalicylaldehyde, forming an insoluble yellow fluorescent product, which indicates the site of thrombin activity [1].

10-(4-(Bis(2-hydroxyethyl)amino)phenyl)-5,5-difluoro-1,3,7,9-tetramethyl-5H-dipyrrolo[1,2-c:2',1'-f][1,3,2]diazaborinin-4-ium-5-uide, a derivative of BODIPY, serves as a fluorescent indicator specifically for the detection of Pb 2+ with an excitation at 504 nM and emission at 510 nM [1] [2].

2-4-(2-Cyanoethyl)(2-phenylethyl)aminophenylazo-5-nitrobenzonitrile is characterized by its storage stability and its fluid, nonagglomerating dispersion properties as an azo dye [1].

Ac-WEHD-pNA serves as a colorimetric substrate for caspases 1, 4, 5, and 14, widely used to assess caspase activity [1].

DMTr-4'-F-5-Me-U-CED phosphoramidite (DMTr-4'-F-5-Methyluridine-CED phosphoramidite) serves as a dye reagent for oligonucleotide labeling, offering effectiveness comparable to native deoxyribonucleoside phosphoramidites. This compound functions as a critical building block [1].

CelRed nucleic acid gel stain 10,000× concentrate in water is a fluorescent dye used for nucleic acid staining, suitable for staining and detecting dsDNA, ssDNA, or RNA in agarose gels or polyacrylamide gels.
