Rp. Iyer et al., IMPROVED PROCEDURE FOR THE REDUCTION OF N-1 CONTENT IN SYNTHETIC OLIGONUCLEOTIDES, Nucleosides & nucleotides, 14(6), 1995, pp. 1349-1357
By incorporating a ''capping step'' at the start of an oligonucleotide
synthesis (''pre-cap'') and following a ''SUP'' work-up protocol with
ammonium hydroxide, an overall improvement is observed in the quality
of oligonucleotides synthesized on a large scale on controlled pore g
lass support (CPG). Rationalization of these results is provided.
