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

The Myc-Luc/EF1α-mCherry reporter cell line (based on NIH3T3) is a genetically engineered mouse embryonic fibroblast cell line derived from NIH3T3 cells. It contains a luciferase reporter gene regulated by a Myc-responsive transcriptional element, allowing researchers to monitor changes in Myc pathway activity by measuring luminescence intensity. Additionally, the cell line constitutively expresses the fluorescent protein mCherry under the control of the EF1α promoter, providing a stable red fluorescent signal for cell identification, visualization, and normalization of experimental data. This dual-reporter system combines dynamic luminescence readouts with a reliable fluorescent marker, while retaining the adherent growth characteristics and standard handling requirements of the parental NIH3T3 cells. It is compatible with standard mammalian cell culture systems and can be used for both endpoint assays and real-time, live-cell analysis.

This reporter cell line is primarily used to study the transcriptional activity of Myc and the regulatory mechanisms of its associated signaling pathways. It is well-suited for screening small-molecule compounds, biological agents, gene expression modulators, and other candidate substances that may activate or inhibit Myc-related responses. Luciferase luminescence intensity provides a sensitive, quantitative measure of pathway modulation, while the mCherry fluorescent signal can be used to assess cell distribution, monitor cell morphology, evaluate the consistency of transfections or treatments, and track changes in cell number. The cell line is also applicable to studies on mechanisms of action, pathway profiling, assay development, and comparative drug testing.
