Separation and Characterization of Oligodeoxynucleotides by FPLC.
The purity of the antisense drugs synthesized by DNA synthesizer should be determined effectively. At pH 12,the oligodeoxynucleotides (ODNs) ranged from 19 bases to 21 bases can be separated successfully on the anion exchange column MONO-Q by elution with a NaCl gradient. The experiments proved that the fast protein liquid chromatography (FPLC) was a useful tool for isolation and identification of the antisense drugs.
