Taurine (2-Aminoethanesulfonic acid)

Taurine is an organic acid found in animal tissues and is a major constituent of bile. Taurine has many biological roles such as conjugation of bile acids, antioxidation, osmoregulation, membrane stabilization and modulation of calcium signaling. Taurine is a biological buffer (zwitterionic) designed by Good, et al., and typically referred to as Good's buffer useful in cell culture media formulations. Selection of biological buffer systems should include the following criteria: exclusion by biological membranes, low absorption between 240 and 700nm, chemically stable, and stable to temperature and concentration changes. , Synonyms: , 1-Aminoethane-2-sulfonic Acid, 2-Aminoethanesulfonic Acid, 2-Aminoethylsulfonic Acid, 2-Sulfoethylamine, NSC 32428, O-Due, Taufon, Taukard, Tauphon, beta-Aminoethylsulfonic Acid, CAS No: 107-35-7, Molecular Formula: C?H?NO?S, Molecular Weight: 125.15, Appearance: White crystalline powder, Purity: 99.0-101.0%, Solubility: Colorless, clear, complete, Residue on Ignition: <0.1%, Loss on Drying: <0.2%, Chromatographic Purity: <0.5%, Chloride: <0.011%, Sulfate: <0.01%, Ammonium: <0.02%, Arsenic: <0.0002%, Iron: <0.001%, Heavy Metals (Pb): <0.001%
