HEK-Lucia™ RIG-I CellsNEW

HEK-LuciaRIG-I cells were generated from HEK-LuciaNull cells, HEK293-derived cells that stably express the secreted Lucia luciferase reporter gene. This reporter gene is under the control of an IFN‑inducible ISG54 promoter enhanced by a multimeric IFN‑stimulated response elements (ISRE). HEK-Lucia™ RIG-I cells stably express high levels of human RIG-I and respond strongly to cytosolic RIG-I ligands such as 3p-hpRNA and 5’ppp‑dsRNA (see validation sheet).

HEK-LuciaRIG-I and HEK-LuciaNull cells can be used to study the role of RIG-I by monitoring IRF-induced Lucia luciferase activity. The levels of IRF-induced Lucia in the cell culture supernatant can be easily monitored using QUANTI-Luc™, a Lucia luciferase detection reagent.

Note: HEK-LuciaRIG-I and HEK-Lucia™ Null cells endogenously express NOD1, TLR3 and TLR5.

HEK-LuciaRIG-I cells are resistant to blasticidinG418hygromycin, and  Zeocin™. They should be maintained in growth medium supplemented with blasticidin and Zeocin™.

RIG-I (retinoic-acid-inducible protein 1, also known as Ddx58) receptor is a cytoplasmic RNA helicase that is critical for host antiviral responses. It senses double-stranded RNA (dsRNA), a replication intermediate for RNA viruses, leading to production of type I interferons (IFNs) in infected cells [1]. Notably, RIG-I detects viral RNAs that exhibit an uncapped 5’-di/triphosphate end and a short blunt-ended double stranded (ds) portion [2]. Upon activation, it is recruited by the adaptor MAVS (also known as IPS-1, CARDIF or VISA) to the outer membrane of the mitochondria leading to the activation of several transcription factors including interferon regulatory factor 3 (IRF3), IRF7 and NF-κB [3]. Activated IRF3 and IRF7 bind to IFN-stimulated response elements (ISRE) in the promoters of IFN-stimulated genes (ISG) leading to a type I IFN‑mediated immune response.
