IL6pro-Luc/EF1α-mCherry Reporter Cell Line - NIH3T3

IL6pro-Luc/EF1α-mCherry Reporter Cell Line - NIH3T3 is a genetically engineered mouse fibroblast cell line derived from NIH3T3 cells, which are widely used in studies of inflammation, cellular signaling, differentiation, and tissue repair. In this reporter system, the luciferase gene is controlled by the promoter region of the mouse interleukin-6 (IL6) gene, allowing activation of the IL6 signaling response to be monitored through a measurable luminescent signal. An EF1α promoter drives constitutive expression of mCherry, providing a stable fluorescent marker for identifying and tracking the cells. The dual-reporter design combines inducible luciferase activity with continuous red fluorescence, supporting both functional analysis and cell visualization.

This reporter cell line is suitable for investigating the regulation of IL6 transcription and evaluating signaling pathways involved in inflammatory responses. It can be used to screen cytokines, inflammatory mediators, small-molecule compounds, biologics, and natural products that either stimulate or suppress IL6-related activity. The system is particularly useful for studying pathways such as NF-κB, MAPK, and other transcriptional networks that contribute to inflammation. Researchers can apply the cells in promoter activity assays, dose-response experiments, pathway inhibitor studies, and high-throughput compound screening. The mCherry signal facilitates fluorescence-based cell counting and quality control, whereas the luciferase readout provides a sensitive and quantitative endpoint for comparing treatment effects. Applications may include inflammation research, immunology, drug discovery, toxicology, and the development of anti-inflammatory therapeutics.
