This product can be hazardous if inhaled or ingested, and should not be handled without gloves or safety glasses.

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.

Acid Blue 260 is a medical dye used in the diagnosis of bowel disease. It is also used to diagnose other inflammatory diseases such as interstitial cystitis and iritis. Acid Blue 260 has been shown to be safe and effective in the treatment of these conditions, with no adverse effects. The clinical relevance of this dye is that it can be used in the diagnosis of diseases that affect children. This dye binds to the polymers found in mucus or epithelial cells by hydrogen bonding, which makes it useful for identifying abnormalities in the lacrimal gland, bowel disease, and other diseases involving inflammation.

Pigment Yellow 175 is a yellow pigment that has a melting point of about 130-140°C. It is soluble in glycol esters and organic solvents, but insoluble in water. The color of Pigment Yellow 175 depends on the type of solvent used. When mixed with deionized water, it appears to be lemon yellow. This pigment can be found in inks, plastics, and rubber products. Pigment Yellow 175 is also used as a colorant for food products.

Applications It has been used to promote wound healing. Biological stain. Dyes and metabolites, Environmental Testing. References Findlay, J., et al.: J. Pharm. Biomed., Anal., 21, 1249 (2000), Han, D., et al.: J. Agric. Food Chem., 55, 6424 (2007), Jiang, Z;., et al.: J. Environ. Anal. Chem., 88, 649 (2008),

C.I. Disperse Orange 25 is a dye that has been used in the textile industry for over 30 years. It is soluble in water and has low toxicity, and is not considered hazardous to health. C.I. Disperse Orange 25 is used as an optical sensor and fluorescent agent in kinetic studies of biological treatment of wastewater, and it can also be used as a reactive or activated antimicrobial agent. The dye can be synthesized using supercritical fluid technology, which makes it a potential candidate for use with radiation-sensitive polymers to form polymer matrices with antimicrobial properties that are resistant to microbial attack by radiation.

Neurodyerh-421 is a polyene antimicrobial agent that has been shown to be effective against Gram-positive and Gram-negative bacteria, including methicillin-resistant strains. Neurodyerh-421 binds to the cell membrane of bacteria and forms an ion channel, causing an influx of sodium ions. This influx leads to the disruption of the membrane potential and eventual cell death. Neurodyerh-421 has also been found to have transport properties that can be modified with sugar residues or by adding ouabain binding compounds. The addition of these compounds enhances the activity and specificity of Neurodyerh-421 as an antimicrobial agent.

Prednisolone 21-hemisuccinate is a synthetic glucocorticoid that has antiinflammatory activity. Prednisolone 21-Hemisuccinate is used in the treatment of inflammatory bowel disease, as well as various other types of inflammatory conditions, such as autoimmune diseases and infectious diseases. It is also used to treat myocardial infarcts and various types of cancer (e.g., leukemia). Prednisolone 21-hemisuccinate acts by binding to the glucocorticoid receptor, which alters gene expression and protein synthesis in cells. Prednisolone 21-Hemisuccinate binds to the Toll-like receptor 4 (TLR4), thereby inhibiting inflammation in mouse models of colitis. Prednisolone 21-Hemisuccinate also decreases glucose levels by decreasing insulin secretion from pancreatic beta cells.

Pigment Red 210 (PR210) is a chemical with an orange-red color. PR210 is a hydroxyl compound with a glycol ether and glycol ester as the major components. It has been used as a control agent for plasma mass spectrometry. PR210 has good chemical stability and does not react with nitrogen atoms. It is also a molecule that consists of particles with a diameter of about 1 micrometer. The radiation from this pigment can cause allergic reactions in some people, and it may be toxic if inhaled or ingested because it can cross-link proteins in the body. PR210 was first synthesized in the 1930s by reacting phenol with 2,4-dichloro-1,3-benzenediol to produce hydroquinone monomethyl ether and 2,4-dichloro-1,3-benzenediol monomethyl ether. The reaction products are then mixed in an acid solution

Fast Violet B is a diazonium salt that reacts with an amine, such as phosphatase, to release hydrogen. This reaction can be used to measure the activity of phosphatases. The emission of light in the visible range depends on the concentration and pH of the solution. Fast Violet B is soluble in water, alcohol, acetone, ether and chloroform. It has a particle size that ranges from 0.1-0.2 microns in diameter and will not dissolve in most solvents. Fast Violet B can be used to detect zearalenone in animal feed samples using a sample preparation technique called thin layer chromatography (TLC). It has shown clinical utility for determining antibody response in humans by measuring fatty acid synthesis activity during the inflammatory response. Fast Violet B also reacts with hydrogen bonds between nucleotides on DNA molecules and it binds to human mitochondrial DNA because it contains many phosphate groups and several intramolecular hydrogen bonds can form between neighboring
