| Bioactivity | ODN 20844, a guanine-modified inhibitory oligonucleotide (INH-ODN), is a TLR7 and TLR9 (Toll-like receptor) inhibitor, and its parent is INH-ODN 2088. ODN 20844 disrupts TLR7- and TLR9-mediated immune cell immune responses. ODN 20844 sequence: 5'-TCCTGGCGc7GGGAAGT-3'[1]. |
| Invitro | ODN 20844 (0.01-10 μM, 24 h) can effectively block TLR9-mediated IFN-α release and inhibit IL-6 secretion in human peripheral blood mononuclear cells[1].ODN 20844 (0.01-10 μM, 24 h) has better inhibitory effect on imiquimod-induced IL-6 secretion in human B cells than INH-ODN 2088[1]. |
