Versuchsvorschrift

This analysis was conducted after the mutein was hydrolyzed in 6N hydrochloric acid containing 4% thioglycolic acid at 110° C. for 24 hours and 48 hours. Cysteine was quantitated as cysteic acid after performic acid oxidation. The values for serine and threonine were obtained by extrapolating the 0-hour value from the 24- and 48-hour values.
