Immobilization of DNA for affinity chromatography and drug-binding studies

A J Macdougall et al. Biochem J. .

Abstract

A method is described in which double-stranded DNA is alkylated with 4-bis-(2-chloroethyl)amino-L-phenylalanine and the product immobilized on an insoluble support via the primary amino group of the phenylalanine moiety. The DNA is hence irreversibly bound to the matrix by both strands at a limited number of points.
