RESUMO
We describe a simple method for specific chemical labeling of DNA fragments at their 3'-termini. The procedure includes enzymatic addition of 4-thiouridine, followed by reaction in mild non-denaturing conditions with the highly reactive alpha-haloacetamido derivatives of several chemical labels. The attached reporter molecule can be removed by extended treatment with beta-mercaptoethanol. Among the potential applications of this labeling method is the study of specific protein-DNA interactions in solution.
