NFκB-Luc/EF1α-mCherry Reporter Cell Line - HeLa

NFκB-Luc/EF1α-mCherry Reporter Cell Line - HeLa is a genetically engineered human cervical cancer cell line designed for sensitive monitoring of NFκB signaling activity. The cells carry a luciferase reporter gene driven by an NFκB-responsive promoter, enabling quantitative measurement of pathway activation through luminescence detection. In addition, the cell line constitutively expresses mCherry under the EF1α promoter, providing a stable fluorescent marker for cell identification, visualization, and normalization. HeLa cells are widely used in cell biology and signal transduction studies because of their robust growth characteristics, high transfection efficiency, and reproducible response to a broad range of stimuli. This dual-reporter system combines inducible NFκB-dependent luminescence with constitutive red fluorescence in a convenient cellular platform for pathway-focused research.

This reporter cell line is suitable for studying inflammatory signaling, innate immune responses, cellular stress pathways, and mechanisms associated with cancer biology. NFκB activation can be induced by cytokines such as TNF-α and IL-1β, microbial components including lipopolysaccharide, oxidative stress, or other pro-inflammatory stimuli, while inhibitory effects can be assessed by measuring reductions in luciferase activity. It is particularly useful for screening small molecules, biologics, natural products, and genetic modulators that regulate NFκB signaling. The constitutive mCherry signal supports live-cell imaging, cell tracking, and evaluation of cell number or viability during assays, helping distinguish pathway-specific effects from changes caused by cytotoxicity or altered cell proliferation. The line can be applied in high-throughput screening, dose-response studies, mechanistic investigations, CRISPR-based functional genomics, and validation of anti-inflammatory or anticancer drug candidates.
