pCpGfree-giant
CDS Ligand – TLR9 Ligand Control
pCpGfree-giant is a high molecular weight plasmid (~15 kb) entirely devoid of CpG dinucleotides and containing AT-rich regions. This DNA also features no detectable amounts of endotoxin, as determined by the LAL assay and the HEK-Blue™-4 cell line-based assay and no detectable TLR2 activity.
In addition, this plasmid DNA displays no Dcm methylation and a reduced level of Dam methylation. pCpG Giant can be used as a control in studies on CpG methylations.
Moreover, when transfected in ISG-reporter cells, pCpGfree-giant induces strong reporter activity. This activity requires STING as cells deficient for STING fail to respond to transfected pCpGfree-Giant. The CDSs of pCpGfree-giant have not been identified yet, but they probably include IFI16 and DDX41.
pCpGfree-giant is also available complexed with the cationic lipid transfection reagent LyoVec™ to facilitate its uptake.
