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.

Ponceau S (Acid Red 112) is an azo protein dye commonly used as a stain in spot blotting assays for protein quantification.

Naphthoresorcinol (1,3-Dihydroxynaphthalene) is a fluorescent dye with an excitation wavelength (λex) of 330 nm and an emission wavelength (λem) of 380 nm.

MitoSOX Red is a novel fluorescent probe that is specific and cell membrane-permeable and targets mitochondria in living cells.MitoSOX Red is oxidized by superoxide upon entry into the mitochondria and is not oxidized by other ROS or RNS-generating systems.MitoSOX Red then binds to nucleic acids in the mitochondrion and produces a strong red fluorescence.MitoSOX Red can be used as a fluorescent indicator for the specific detection of superoxide.MitoSOX Red can be used as a fluorescent indicator for the specific detection of superoxide. MitoSOX Red can be used as a fluorescent indicator to specifically detect superoxide. Superoxide dismutase (SOD) prevents the oxidation of MitoSOX Red.

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.

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.

Nile Red (Nile Blue A oxazone) is a strongly fluorescent stain used for the detection of intracellular lipid droplets in the presence of a hydrophobic environment.

C.I. Pigment Red 172 (C.I. Food Red 14:1) is a food additive.

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

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.

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.

MitoSOX Red TFA (Mito-hydroethidine TFA) is a fluorescent probe that specifically targets mitochondria in living cells.MitoSOX Red is susceptible to oxidation by superoxide, but is not easily oxidized by other ROS or RNS-generating systems.MitoSOX Red acts as a fluorescent indicator and can be used for live cell imaging.

Red-HyP-1 is a red dye that can be used for in vivo hypoxia imaging. The maximum emission maximum of Red-HyP-1 is 798 nm.

ATP-Red 1 is a fluorescent probe with good membrane permeability that selectively and rapidly responds to intracellular ATP concentrations in live cells.

Phenol Red sodium salt is a water-soluble pH indicator used in the range from 6.8 (yellow) to 8.2 (red).

Trypan red is a vital dye.

C.I. Disperse Red 15 is a red dye. C.I. Disperse Red 15 is used as a fluorescent indicator.

Acridine red is an indicator of fluorescent.

D & C Red no. 31 is an agent of dye.

D&C Red No. 27 Aluminum Lake is a drug and cosmetic synthetic dye. The FDA lists it as a safe additive for drugs and cosmetics as per FDA standards.

Methyl red, an azo dye, serves as a pH indicator, transitioning from red at a pH of 4.4 to yellow at a pH of 6.0.

DQ-BSA-Red is a bovine serum albumin (BSA) molecule labeled with a red fluorescent dye, designed for monitoring lysosomal activity. The excitation and emission wavelengths of DQ-BSA-Red are 590 nm and 620 nm, respectively. The BSA in DQ-BSA-Red is heavily tagged with the red fluorescent dye at multiple sites, leading to significant fluorescence self-quenching. Upon entry into the lysosome, DQ-BSA is cleaved by lysosomal proteases, resulting in the unquenching and release of fluorescent fragments that emit bright fluorescence. Conversely, functionally inactive lysosomes fail to degrade the BSA protein, thereby displaying lower or no fluorescence signal.
