The isolation of duplex DNA fragments containing (dG.dC) clusters by chromatography on poly(rC)-Sephadex.
Duplex DNA containing oligo(dG.dC)-rich clusters can be isolated by specific binding to poly(rC)-Sephadex. This binding, probably mediated by the formation of an oligo(dG.dC)rC+ triple helix, is optimal at pH 5 in 50% formamide, 2 M LiCl; the bound DNA is recovered by elution at pH 7.5. Using this m...
