Alexa fluor 647 NHS ester (L-5-Hydroxytryptophan-d3) is a photostable far-red fluorescent dye used in imaging and flow cytometry to generate stable signals for protein labeling, amine-modified oligonucleotides, and other primary amine-containing molecules.

Fast red TR salt hemi(zinc chloride) is a red diazo dye with λmax = 284 nm, commonly used as a chromogenic substrate for alkaline phosphatase (AP) and in immunohisto-chemistry to detect specific proteins or antigens in tissue sections.

Phenol Red (Sulfonphthal) is a pH indicator, red dye, and diagnostic aid for measurement of renal function. It is used also for researches of the gastrointestinal and other systems.

Alizarin Red S sodium (ARS sodium) is an anthraquinone dye widely used to evaluate calcium deposits in cell culture[1].

Congo Red (Direct Red 28) is an azo dye. It binding been used as a diagnostic test for the presence of amyloid in tissue sections.

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.

Rhodamine 6G (Basic Red 1) is a rhodamine analog useful in Pgp efflux assays. It can be widely used in characterizing the kinetics of MRP1- mediated efflux as a laser dye and potential mitochondrial probe.

Neutral red is a vital dye, is used as an indicator and biological stain.

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

Betanin (Betanine) is a natural red-violet food dye obtained from beets.

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

Sudan III (Solvent Red 23) is a solvent dye used to color nonpolar substances.

Acridine Orange base is a cell-permeable fluorescent dye that binds to nucleic acids and emits different colors of fluorescence, which exhibits green fluorescence when bound to dsDNA (Ex=488 nm, Em=520-524 nm) and red fluorescence when bound to ssDNA or ssRNA (Ex=457 nm, Em=630-644 nm) and can be used for cell cycle analysis and apoptosis detection.

Amaranth (Acid Red 27) as a potential component of lifestyle modification to improve cardiovascular risk profiles by modifying cardiovascular risk factors such as cholesterol, diabetes, and hypertension.

Nuclear Fast Red is an anthraquinone dye that serves as a red nuclear counterstain when aluminum ions are present in excess, thereby aiding in histological visualization of nuclear components. Nuclear Fast Red additionally functions as a histochemical and colorimetric reagent for calcium detection,Nuclear Fast Red further acts as a highly sensitive “off/on” fluorescent probe for the detection of guanine, making it a multifunctional research reagent.

The dry dye Oil red O is used for the preparation of a staining solution that can be used for the detection of lipids in histological cryo sections.

Safranin O (Basic red 2) stains the lignified, embolic and keratinized parts of the plant, as well as chromatin and chromosomes in the nucleus. Safranin O is commonly used for the detection of cartilage, mucin and mast cell granules.

Carmine (Carmine red) is an azo dye derived from dried Dactylopius coccus var. Costa and is an added food coloring.Carmine causes immediate hypersensitivity and delayed systemic reactions.3-Phosphoglyceric acid (Glycerate 3-phosphate) is a glycolic acid derivative involved in glycolysis and the Calvin cycle, and in the epigenetic regulation of alveolar macrophages.

Sudan IV (Solvent Red 24) is a lysochrome (fat-soluble dye) diazo dye used for the staining of triglycerides,lipids and lipoproteins on frozen paraffin sections.

Carminic acid, the well-known red dyestuff from cochineal insects (Dactylopius spp.), is a potent feeding deterrent to ants. Carminic acid is an antioxidant to protect erythrocytes and DNA against radical-induced oxidation, it also has antitumor activity.
