摘要: Confocal microscopy was used for the measurement of plasmid DNA adsorbed to individual adsorbent particles intended anion-exchange and triple helix affinity chromatography. Plasmid visualized with fluorescent dye YOYO-1, that forms a highly complex double stranded DNA. images were translated into fluorescence intensity profiles distribution in measured. The results adsorption mainly takes place an outer layer particles. described procedure can also be advantageously demonstrate formation between immobilized oligonucleotides.
