A Simple and Stable Silica Gel Support for the Oligodeoxyribonucleotide Synthesis

Abstract
A simple and efficient synthesis of a solid support with a long chain polyamide spacer has been developed. The spacer was made by successive addition of ethylene-diamine and succinic anhydride. The obtained solid support gives very homogeneous 20 mer oligodeoxyribonucleotides, detected by HPLC and electrophoresis.
