WebDegradation of a 25-mer PS oligonucleotide having a S P-phosphorothioate linkage at the 3′ terminus has been reported to be more than 300 times slower than an analog with a 3′-terminal PS linkage of R P configuration. The uptake of phosphorothioate oligonucleotides has been described to be similar to “natural” oligonucleotides.
