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

TNFαPro-Luc/EF1α-mCherry Reporter Cell Line - NIH3T3 is a genetically engineered mouse embryonic fibroblast cell line derived from NIH3T3 cells. It contains a luciferase reporter gene controlled by the promoter region of tumor necrosis factor alpha (TNFα), allowing TNFα promoter activity to be monitored through a quantifiable luminescent signal. The cell line also constitutively expresses mCherry under the control of the EF1α promoter, providing a stable fluorescent marker for identifying and tracking the cells. With the biological characteristics of NIH3T3 fibroblasts and dual luciferase–fluorescence readouts, this reporter system offers a convenient and sensitive platform for studying inflammatory signaling and transcriptional regulation. Luciferase activity generally reflects changes in TNFα promoter activation, while mCherry fluorescence can be used for cell localization, transfection assessment, and normalization of cell numbers.

This reporter cell line is suitable for investigating the molecular mechanisms that regulate TNFα expression in inflammatory and immune-related pathways. It can be used to evaluate the effects of cytokines, pathogen-associated stimuli, small-molecule compounds, biologics, and gene-editing approaches on TNFα transcriptional activity. The system is particularly useful for screening anti-inflammatory drugs and identifying compounds that either suppress or enhance TNFα-related signaling. Researchers may also apply it to study the activation of pathways such as NF-κB, MAPK, and other transcriptional networks involved in inflammatory responses. In addition, the line supports high-throughput screening, promoter activity analysis, pathway validation, and comparative assessment of treatment conditions. The mCherry signal provides an independent visual reference, helping distinguish changes in reporter activity from variations caused by cell density, viability, or experimental handling.
