title: Improved application of the diphenylamine reaction for the determination of DNA.
abstract: An improved procedure is described for the separation and quantitation of DNA from biological samples. Following papain digestion, DNA was separated from other cell material with CdCl2 precipitation onto a glass-fiber filter and quantitated easily by the modified diphenylamine reaction.
