We have synthesized and studied the effects of phosphorothioate (PS) oligodeoxyribonucleotide (DNA) and oligoribonucleotides (RNA, 2'-O-methyl-RNA and 2'-5'-RNA) on complement activation and prolongation of activated partial thromboplastin time (aPTT) in vitro. These results suggest that a PS-DNA prolongs aPTT, and inhibits complement lysis more than do the PS-RNA analogs.
