Neutral-ODN (Control for iODNs) (endotoxin-free) (synthetic)

Inactive (neutral) control ODN for in vivo use in rodents (50-150µg per injection) without agonistic nor antagonistic activity.

Several groups have studied the sequence requirements, specificity, signalling pathways and kinetics of the TLR (Toll-like receptor) 9 suppression by ‘inhibitory DNA motifs’, which led to a revised classification of iODNs, that is independent of the previously thought species preference.Class I: G-stretch ODNs: TLR9-specific competitors, some iODNs may also affect TLR7 and TLR8 signalingClass II: ODNs with telomeric repeats: TLR-independent inhibitors of STAT signalling (cellular uptake via an “ODN receptor”?)Class III: Inhibitors of DNA uptake in a sequence independent mannerClass IV: Long phosphorothioate ODNs as direct competitors of TLR9 signaling in a sequence independent mannerSlightly modified phosphodiester versions of the most potent inhibitory ODNs were also able to profoundly block the immune activation of macrophages and proved to be valuable tools for in vivo use in experimental animal models of inflammatory and auto-immune diseases.
