Abstract: | The use of Reversed-Phase High Performance Liquid Chromatography (RP-HPLC) was investigated for the separation of oligonucleotides.
By the gradient elution with the mobile phase of methanol, 0.1 M KH2PO4 and 0.02 M MaCl2, the mixtures could be separated in a 250 mm × 4.6 mm I.D. column. The number of theoretical plates and resolution were compared
belween this technique and Micellar Electrokinetic Capillary Chromatography (MECC). The charged nucleic acid constituents
in the RP-HPLC were relatively better separated than in the MECC. |
