RAW-Lucia™ ISG-KO-IRF7 Cells

IRF7 knockout IRF-inducible Lucia luciferase reporter mouse macrophages

RAW-Lucia^™ ISG-KO-IRF7 cells were generated from RAW-Lucia^™ ISG cells through the stable gene knockout of interferon regulatory factor 7 (IRF7), a key transcription regulator of type I interferon (IFN)-dependent immune responses. These cells derive from the murine RAW 264.7 macrophage cell line, which has been reported to express many pattern recognition receptors (PRRs), including Toll-like receptor 9 (TLR9) [1, 2]. Stimulation of TLR9 with CpG-containing oligonucleotides (CpG-ODNs) induces the formation of a complex consisting of MyD88, TRAF6 and IRF7 leading to the production of type I IFNs.

RAW-Lucia^™ ISG-KO-IRF7 and RAW-Lucia^™ ISG cells can be used to study the role of IRF7 in a mouse macrophage cell line by monitoring of interferon regulatory factor (IRF)-induced Lucia luciferase activity. They express the gene for secreted Lucia luciferase under the control of the I-ISG54 promoter which is comprised of the IFN-inducible ISG54 promoter enhanced by a multimeric ISRE. The levels of IRF-induced Lucia in the cell culture supernatant can be easily monitored using QUANTI-Luc^™, a Lucia luciferase detection reagent.

RAW-Lucia^™ ISG-KO-IRF7 cells are resistant to Zeocin^™.
