title: Use of immobilized triazine dyes in the purification of DNA topoisomerase I (Topo I) and terminal deoxynucleotidyl transferase (TdT) from calf thymus.
abstract: The interaction between TdT and Topo I, and twelve various triazine dyes immobilized on Sepharose CL-6B was studied. Yellow lightproof 2KT-Sepharose and Bordeaux 4ST-Sepharose were used to purify TdT and Topo I, respectively. The principal role of copper ions, complexed to the dye molecules, in the dye-protein interaction was evaluated.
