Bj. Turney et al., Stability of phosphorothioate oligonucleotides in aqueous ammonia in presence of stainless steel, NUCLEOS NUC, 18(1), 1999, pp. 89-93
Oligodeoxyribonucleotide phosphorothioates undergo desulfurization in prese
nce of metal in aqueous ammonia at elevated temperatures. The extent of sul
fur loss and chain cleavage have been investigated.
