✦ Synopsis

A significantly improved method for base composition analysis of synthetic oligodeoxyribonucleotides is presented. This highly accurate and sensitive method uses enzymatic digestion followed by high-resolution HPLC of the nucleosides to determine the empirical base composition of the parent compound. The enzymatic digestion reaction is quantitative and is not blocked by modified bases, thus allowing the degree of base deprotection and chemical modification to be assessed. Digestion data are presented for oligodeoxyribonucleotides which range from 18 to 150 bases in length with excellent agreement of experimental and theoretical composition. The method is also applicable to high-molecular-weight genomic DNA. o 1987 Academic Prw, Inc.
