A method is described for determining riboflavin 5'-phosphate (FMN) and flavin adenine dinucleotide (FAD) in mixtures by fluorimetric titration with the FMN-specific apoprotein of flavodoxin from Peptostreptococcus elsdenii. Accurate determinations can be carried out in the presence of a variety of

✦ Synopsis
A modification of a calorimetric assay (1) discriminating galactosamine and glucosamine in mixtures is presented. The procedure employs acetylation of the amino sugars at 25°C instead of at 0-i"C, resulting in five times the color intensity for galactosamine with no interference due to glucosamine. The assay of HCI hydrolysates of glycosaminoglycans and glycoproteins is possible in solutions that are less than 0.1 N.
