Abstract

In the presence of acid, the 2-deoxypentose of DNA is converted to beta-hydroxylevulinaldehyde which reacts with diphenylamine to give blue color, which is estimated by UV spectrophotometer or by colorimeter at 595 nm. Since only deoxyribose of purine nucleotide reacts, the value obtained represents only half to total amount.
