dye

D149 Dye is an indoline-based, high-extinction-coefficient, metal-free organic sensitizer.

Dye 937 is substituted unsymmetrical cyanine dyes and useful in the detection of DNA in electrophoretic gels.

Dye 993 is substituted unsymmetrical cyanine dyes and useful in the detection of DNA in electrophoretic gels.

Heptamethine cyanine dye-1, a near-infrared cyanine dye, is used for fluorescence imaging in biological systems.

NIR dye-1 is a near-infrared (NIR) fluorescent dye which has absorption and emission in the NIR region while retaining an optically tunable hydroxyl group.

Lac dye is a possible food coloring agent which is completely nontoxic at low doses; lac dye is water soluble constituent of stick lac (commercial lac resin); lac resin is hardened secretion of insect Laccifer lacca (lac insect).

Endoplasmic reticulum dye 1 is a highly effective live cell imaging agent used to detect exocytotic events at the plasma membrane. The compound exhibits minimal cytotoxicity and is resistant to photobleaching, making it ideal for visualizing short- and long-term processes.

Cy5-bifunctional dye is a derivative of CY5. CY5 is an amine-reactive fluorophore with excitation/emission wavelengths of 650/670 nm, commonly employed for labelling nucleic acids and proteins.

ROX Reference Dye is an inert fluorescent dye used in real-time PCR (qPCR) or RT-PCR to normalize fluorescence signals between wells. It does not participate in the PCR reaction and maintains a stable fluorescence signal throughout the process。ROX dye can correct for variations in fluorescence signals caused by uneven lighting, differences in well optics (such as droplets, bubbles), and variations in reaction mixture concentration。

CY5-SE (Cy5 NHS Ester) is a reactive dye used to label amino groups in peptides, proteins and nucleotides. It needs to be stored away from light. Excitation wavelength (nm): 640, emission wavelength (nm): 664.

Azure B (Azure B chloride) is a cationic dye and the major metabolite of Methylene blue. Azure B is a selective, and reversible inhibitor of MAO-A (IC50s: 11 and 968 nM for recombinant human MAO-A and MAO-B).

Ninhydrin is a chromogenic analytical probe for the quantification of proteins and amino acids.

Solvent Yellow 93, an azomethine dye, is used as a colorant of toner.

AMI5 (Eosin Y Disodium) is a soluble acidic red dye molecule. It is commonly used as a photoredox catalyst in organic synthesis.

Acid Yellow 36 (Metanil Yellow) is an azo dye and pH indicator, changing color from red at pH 1.2 to yellow at pH 2.3.

Ruthenium Red (Ammoniated ruthenium oxychloride) is a polycationic dye widely used for electron microscopy (EM) of cells, tissues and vegetative bacteria. Ruthenium red strongly reacts with phospholipids and fatty acids and binds to acidic mucopolysaccharides. Ruthenium red is a L-type calcium current (ICa) blocker, blocks Ca2+ uptake and release, and voltage-sensitive Ca2+ channels

Disperse Red 1 (Celliton Scarlet B) is an azo dye that contributes to the toxicity and pollution of wastewater.

Methylene Blue (Tetramethylthionine chloride) (IC50 of 1.9 μM) inhibits tau filament formation. And it inhibits soluble guanylyl cyclase. It is also used as a dye in chromoendoscopy.

Stains-All is a cationic dye of carbocyanine.

Calcein Blue is a blue-fluorescent, short-term dye.

Acid orange 7 (COLIPA C015) is a dye used to dye wool.

AkaLumine hydrochloride is a fluorescein analog with a Km value of 2.06 μM for recombinant fluorescent protein.

Ponceau 4R (Acid Red 18) is a synthetic strawberry red azo dye that is a food colorant dye used in a variety of food products. It is stable to light, heat and acid, but fades in the presence of ascorbic acid. It is usually synthesized from aromatic hydrocarbons.

IR-820 (New Indocyanine Green) is a near-infrared dye with improved stability, good color rendering, and excellent fluorescence penetration. It serves as an infrared blood pool contrast agent for detecting and quantifying diseased tissue in live animals, with maximal excitation (Ex) and emission (Em) of 710 and 820 nm, respectively.
