Substances used for the detection, identification, analysis, etc. of chemical, biological, or pathologic processes or conditions. Indicators are substances that change in physical appearance, e.g., color, at or approaching the endpoint of a chemical titration, e.g., on the passage between acidity and alkalinity. Reagents are substances used for the detection or determination of another substance by chemical or microscopical means, especially analysis. Types of reagents are precipitants, solvents, oxidizers, reducers, fluxes, and colorimetric reagents. (From Grant & Hackh's Chemical Dictionary, 5th ed, p301, p499)

使用A redox indicator dye.
純化方法Dissolve it in 0.001M phosphate buffer, pH 7.5 (alternatively, about 2g of the dye is dissolved in 80mL of M HCl), and extracted into diethyl ether. The extract is washed with water, extracted with aqueous 2% NaHCO3, and the sodium salt of the dye is precipitated by adding NaCl (30g/100mL of NaHCO3 solution), then filtered off, washed with dilute NaCl solution and dried. It has max at 605nm. [Hiromi et al. Anal Biochem 101 421 1980.] The acetate M 310.1 has m 101-103o (from Et2O/pet ether) and 99.5-100.5o (from Et2O). [Beilstein 13 IV 1078-1079.]
