Isoamy alcohol is routinely used in molecular biology, especially in the purification of DNA. It is widely used in conjunction with phenol and chloroform (25:24:1 phenol : chloroform : isoamyl alcohol) for the removal of proteins from the nucleic acid solutions by extraction. Isoamyl alcohol is…

Ethyl acetate is used primarily as a solvent and diluent. Ethyl Acetate is suitable for HPLC, spectrophotometry, environmental testing.

Acetic anhydride is a reagent that is used in the manufacturing of acetyl compounds and cellulose acetates. It is also utilized as a solvent in the examination of wool fat, glycerol, fatty and volatile oils, and resins. In the synthesis of organic compounds, acetic anhydride is used in various…

Hydrochloric acid is used as a laboratory reagent, for pickling of steel, in production of organic and inorganic compounds, for pH control and neutralization, used in the regeneration of ion exchange resins, in the production of food, food ingredients, and food additives. Chlorine source for safer,…

Polyethyleneimine is a branched chain polymer having a ratio of 1:2:1 of primary:secondary:tertiary amines with a branching site every 3 to 3.5 nitrogen atoms and a base structure of (CH₂CH₂NH)x. The nitrogen atoms must be protonated to achieve cationic charge, so the cationic…

Polysorbate 20 is typically used as an emulsifying agent for the preparation of stable oil-in-water emulsions, particularly in pharmaceutical applications. It has been used in pre-extraction of membranes to remove peripheral proteins. It has been used as a blocking agent on nitrocellulose. …

Dimethyl sulfoxide (DMSO) is a highly polar aprotic organic reagent that has exceptional solvent properties for organic and inorganic chemicals. Dimethyl Sulfoxide is ideal for use as a cryoprotectant. Also used in chemical reactions, in polymerase chain reactions (PCR) as a PCR cosolvent to…

Ammonium acetate is a chemical compound which is derived from the reaction of ammonia and acetic acid. Ammonium acetate is volatile at low pressures. Because of which it has been used to replace cell buffers with non-volatile salts, in preparing samples for mass spectrometry. It is used as a buffer…

Tween 80 is a polyethylene sorbitol ester, non ionic surfactant and an emulsifier derived from polyethoxylated sorbitan and oleic acid. Tween 80 has been widely used in biochemical applications including: solubilizing proteins, isolating nuclei from cells in culture, growing of tubercule…

2-Mercaptoethanol is a hybrid of ethylene glycol and 1,2-ethanedithiol. It is used to reduce disulfide bonds and can act as a biological antioxidant by scavenging hydroxyl radicals. It is widely used because the hydroxyl group confers solubility in water and lowers the volatility. Due to its…

2-Merceptoethanol is used to reduce disulfide bonds and can act as a biological antioxidant by scavenging hydroxyl radicals. 2-Merceptoethanol is used to reduce disulfide linkages in solubilizing proteins for gel electrophoresis. 2-mercaptoethanol is readily oxidized in air to a disulfide,…

n-Butanol is useful for the removal of ethidium bromide from DNA purified by CsCl gradient ultracentrifugation. It is also suitable for use in the concentration of dilute nucleic acid solutions by repeated extractions. Increased nucleic acid concentration improves recovery by ethanol precipitation.

A mineral oil is any of various colorless, odorless, light mixtures of alkanes in the C15 to C40 range from a non-vegetable (mineral) source, particularly a distillate of petroleum.Most often, mineral oil is a liquid by-product of the distillation of petroleum to produce gasoline and other…

Glycerol triacetate is used as a food additive and as a solvent in flavorings. It acts as an excipient in pharmaceutical products where it is used as a humectant and a plasticizer. It is also used as a fuel additive, as an antiknock agent, adhesives and sealant chemicals, fillers, intermediates and…

Safflower oil is a raw oil without preservative. Safflower oil is used for preventing heart disease, including “hardening of the arteries” (atherosclerosis) and stroke. It is also used to treat fever, tumors, coughs, breathing problems, clotting conditions, pain, heart disease, chest…

Sesame oil is a potent antioxidant, which can inhibit DNA damage and lipid peroxidation by 4-Nitroquinoline N-oxide in rats. Studies indicate that Sesame oil can increase wound healing in SKH1 mice when added together with ozone. It is known that Sesame oil is composed of triacylglycerols…

Squalene, an isoprenoid compound structurally similar to beta-carotene, is an intermediate metabolite in the synthesis of cholesterol. Squalene is not very susceptible to peroxidation and appears to function in the skin as a quencher of singlet oxygen, protecting human skin surface from lipid…
