WebWe have previously shown that an oligo(nucleoside methylphosphonate) (deoxynucleoside methylphosphonate residues in italics) complementary to the … WebHistorically, methylphosphonate oligonucleotide synthesis has been inefficient, costly, and difficult to conduct above a l-µmol scale. We have devised methods that significantly reduce cost, increase coupling efficiency, improve recovery, and are applicable to larger-scale synthesis.
