NF-Kb Luciferase Reporter Lentivirus

The NF-κB luciferase reporter lentivirus is a versatile, ready-to-use vector system designed to convert NF-κB pathway activity into a robust and quantifiable luminescent signal. Built on a modern self-inactivating lentiviral backbone, this system couples a minimal promoter with tandem NF-κB response elements upstream of the luciferase gene, resulting in low basal expression, high inducibility, and an excellent signal-to-noise ratio. Because lentiviral vectors stably integrate into the host genome, this reporter gene supports long-term studies, the generation of clonal cell lines, and stable data acquisition across generations. Its broad host cell tropism allows for efficient transduction of a wide variety of cell types, including many primary cells and difficult-to-transfect cells, while the minimal promoter structure reduces background signal, revealing subtle differences in pathway activation.

This reporter gene is ideally suited for basic research, translational research, and drug discovery, particularly in applications where NF-κB is a key node. In cell biology and immunology, it enables quantitative monitoring of inflammatory signal transduction and feedback control, supporting studies on receptor binding, adaptor protein function, and downstream transcriptional regulation. In disease modeling, it helps elucidate the role of NF-κB in chronic inflammation, autoimmunity, metabolic dysfunction, neuroinflammation, and tumor-associated signaling in the tumor microenvironment. Drug discovery teams can utilize this reporter gene to analyze small molecules or biologics that modulate pathway components, build high-throughput screening platforms for identifying inhibitors or activators, and generate precise dose-response curves and kinetic profiles for hit compound screening and mechanism of action assessment.
