Indophenol blue is a dye that is used in laboratories to identify the presence of protein. It is used to detect proteins in biological samples such as human serum, which can be done through immunoassays or polymerase chain reaction (PCR) techniques. Indophenol blue reacts with proteins by oxidizing them and changing their color from blue to pink. The optimum concentration for this reaction to take place is 1-2mg/mL of hydrochloric acid and 0.5-1% sodium citrate. The redox potential of the reaction solution must be negative, so it can reduce the indophenol blue back to its original form. This chemical reaction is also used in surface methodology, where a drop of solution is added on an object's surface and then heat-treated to produce a change in coloration.

Glutathione is a tripeptide cysteine-glycine-glutamic acid which exists in cells in the reduced form (this product) or oxidised form. Reduced glutathione (GSH) is an antioxidant protecting cell components from endogenous and exogeneous reactive oxygen and nitrogen species. Reduced glutathione has also been intensely used in the affinity purification of proteins with glutathione S-transferase (GST) tag. In the protein purification process, glutathione is used for the elution of GST-fused recombinant proteins from a glutathione-immobilised resins. In the elution buffers, reduced glutathione is typically used in the 10 – 40 mM concentration range.

The dye can also be used in wastewater treatment because it can reduce the amount of bacteria present by absorbing light energy from ultraviolet radiation. Disperse Blue 14 has also been shown to bind with fatty acids, which are known for their ability to activate reactive oxygen species (ROS). This reactive property may be due to its ability to bind with styryl dyes, which are often activated by UV radiation or heat. A molecular docking analysis was conducted using Disperse Blue 14 and found that it binds with the electron-rich region of cytochrome c oxidase, a protein involved in respiration in mitochondria. This binding inhibits electron transfer between cofactors Q and cytochrome c oxidase

Glutathione-diethyl ester (GDE) is a reactive molecule that can be reduced to glutathione (GSH) in vivo. GDE has been shown to have DNA binding activity and can act as a model system for nuclear dna. It is also an antioxidant with transport properties that are studied by fluorescence analysis in cellular systems. GDE has been shown to reduce oxidative damage to DNA, which may be due to its ability to scavenge free radicals. This molecule also has antioxidative activity against human macrophages, cancer cells, and neuronal death caused by oxidative stress. Synthetic antioxidants such as butylated hydroxytoluene (BHT) can inhibit the pro-oxidant effects of GDE on mitochondrial membrane potential, suggesting that it may have pro-oxidant activities as well.
