THP1-Lucia™ ISG Cells

THP1-Lucia™ ISG cells were derived from the human monocytic cell line THP-1, which represents a model of choice to study the activation and signaling of CDSs.
Indeed, THP-1 cells have been shown to express all the CDSs identified so far [1-3], with the exception of DAI [4].

THP1-Lucia™ ISG cells express the secreted luciferase (Lucia) reporter gene under the control of an IRF-inducible promoter. This composite promoter is comprised of five IFN-stimulated response elements (ISRE) fused to an ISG54 minimal promoter, which is unresponsive to activators of the NF-kB or AP-1 pathways. As a result, THP1-Lucia™ ISG cells allow the monitoring of the IRF pathway by determining the activity of Lucia luciferase. The levels of IRF-induced Lucia luciferase in the cell culture supernatant are readily assessed with QUANTI-Luc™, a luciferase detection reagent.

THP1-Lucia™ ISG cells are resistant to Zeocin™.
THP1-Lucia™ ISG cells are highly responsive to STING and CDS ligands, such as transfected double-stranded nucleic acids.
