| Abstract |
The use of an amino-silica column in the chromatographic analysis of synthetic oligodeoxyribonucleotides and their derivatives from different stages of oligonucleotide synthesis has been investigated. By eluting with 0.10 M potassium phosphate solution of pH 3.30, the nucleotide composition of oligonucleotides can be established within 15 min. In a linear gradient of phosphate buffer (0.10-0.75 M) at neutral pH, the separation of oligonucleotides by length and in an acidic medium pH 3.30-4.30) by composition is possible; the oligonucleotides may be in the free form or modified by the various protecting groups used in synthetic oligonucleotide chemistry. The analysis of some reaction mixtures from different stages of oligonucleotide synthesis and of a number of synthetic oligodeoxyribonucleotides and their derivatives has been performed. |
