NFκB-Luc/EF1α-mCherry Reporter Cell Line - NIH3T3

NFκB-Luc/EF1α-mCherry Reporter Cell Line - NIH3T3 is a genetically engineered mouse fibroblast reporter cell line derived from the widely used NIH3T3 cell background. The cell line contains a firefly luciferase reporter gene under the control of an NFκB-responsive promoter, enabling quantitative measurement of NFκB transcriptional activity through luminescence detection. It also constitutively expresses mCherry under the EF1α promoter, providing a stable fluorescent marker for visual identification, cell tracking, and normalization of cell number or transfection-related variations. By combining a sensitive luminescent readout with red fluorescence, this reporter line supports convenient monitoring of pathway activation while maintaining the characteristic growth properties and experimental versatility of NIH3T3 cells.

This reporter cell line is designed for studies of NFκB signaling and its regulation in inflammatory, immune, stress-response, and cell-survival processes. It can be used to evaluate the activity of cytokines, microbial components, receptor agonists, chemical compounds, and other stimuli that activate or inhibit the NFκB pathway. The system is also suitable for screening anti-inflammatory drugs, pathway inhibitors, gene overexpression constructs, siRNA or CRISPR-based perturbations, and potential therapeutic molecules. Luciferase measurements provide a sensitive and scalable endpoint for dose-response studies, kinetic analysis, and medium- to high-throughput screening, while mCherry fluorescence assists with cell localization, viability assessment, and assay quality control. Researchers may apply this cell line in pathway mechanism studies, compound screening, reporter assay development, and validation of NFκB-related targets.
