Other Labeling Dyes

Fluorescent red 610 is a fluorescent dye with an excitation peak at 590 nm and an emission peak at 610 nm.

Dansyl ethylenediamine is a fluorescent probe. Dansyl ethylenediamine can be used for synthesis of protein-imprinted polymers which is capable of specific transduction of protein binding events into fluorescent signal change.

3,3'-Diethylthiacyanine iodide is a cyanine fluorescent dye. 3,3'-Diethylthiacyanine iodide manifestes a pronounced affinity for bacterial cells.

1,2-Diamino-3,4-ethylenedioxybenzene is a carbonyl-reactive fluorometric labeling agent.

6,7-Diaminoquinoxaline-2,3-dione dihydrochloride is a fluorescent dye that reacts with aldehydes.

2,7-Bis(alloxycarbonylamino)-9-chloroacridine can be used as a fluorescent label.

GA-PEG5-bromide is a probe used for molecular labeling.

HM Janelia Fluor 526, SE (HM-JF526 NHS) is a derivative of hydroxymethyl JF526 (HM-JF526). SMLM (single-molecule localization microscopy) imaging in standard phosphate-buffered saline (pH 7.4) revealed that the HM-JF526 label showed spontaneous blinking behavior throughout the imaging session and did not require short-wavelength activation light. Janelia Fluor fluorescent dyes can be chemically conjugated to the specific HaloTag substrate (a chloroalkane ligand) to form a fluorescent ligand, rather than binding directly to the HaloTag protein itself. Janelia Fluor products are licensed under U.S. Pat. Nos. 9,933,417, 10,018,624 and 10,161,932 and other patents from Howard Hughes Medical Institute.

C6 NBD L-threo-dihydroceramide is a dihydro-ceramide isomer labeled with a fluorescent group C6 nitrobenzoxadiazole (C6 NBD), can be used to detect ceramide.

Alexa Fluor 430 NHS ester is a compound that couples green fluorescent dye Alexa Fluor 430 to a protein or antibody. Alexa Fluor 430 is used for the generation of stable signals in imaging and flow cytometry. NHS ester can be used to label proteins, amine-modified oligonucleotides and other primary amines (R-NH2) containing amine molecules.

AF594 DBCO is an AlexaFluor 594-conjugated DBCO click chemistry probe for fluorescent labeling of azido-modified cholesterol probes. DBCO is a commonly used chemical biomarker group. AF594 DBCO (Excitation wavelength about 590 nm, emission wavelength about 617 nm) can be used to label proteins, cells and other biomolecules for fluorescence imaging and flow cytometry detection.

AF555 NHS is a red fluorescent dye with excellent fluorescence properties and light stability. The excitation wavelength is 556 nm and the emission wavelength is 571 nm, which can be used for protein labeling, antibody labeling, and cell imaging.
