✦ Synopsis

2. 227 mg of cysteamine and 392 mg of Mohr's salt are dissolved in 50 ml of 1 M tris-HC1 buffer (pH = 7.0). The p H is then adjusted to 9.5 by 1 N NaOH, and a solution of 504 mg of the sodium salt of riboflavin monophosphate (FMN) in 25 ml of H 2 0 is added. After 5 minutes the mixture is transferred to an ESR sample tube, frozen, and measured. In this case absorption by the flavosemiquinone at g = 2.00 also occurs (see Fig. lb). (b) By oxidation of tricarbonyl(cystine dimethyl ester)iron(0) [51: 0.2 ml of a 10-2 M ethereal solution of the cystine dimethyl ester-iron(0) complex is treated in an ESR sample tube with 5 mg of solid iodine, frozen after 20-seconds' shaking, and measured.
