Mercaptpalbumin and nonmercaptoalbumin were analyzed using Asahipak ES-502N (a column for weak anion exchange chromatography). The ratio of human mercaptoalbumin (HMA) to human nonmercaptoalbumin (HNA) in serum is thought to have some relation with aging. The correlation between the ratio and various types of illness is being studied.
