NFκB-Luc/EF1α-mCherry Reporter Cell Line - T24

The NFκB-Luc/EF1α-mCherry Reporter Cell Line - T24 is a dual-reporter system established within the T24 human urinary bladder carcinoma background to facilitate the precise monitoring of Nuclear Factor kappa B (NF-κB) transcriptional activity. This cell line contains a firefly luciferase gene driven by a minimal promoter and multiple NF-κB response elements, allowing for highly sensitive bioluminescent detection of pathway activation in response to various stimuli. To facilitate data normalization and cell tracking, the red fluorescent protein mCherry is constitutively expressed under the control of the human EF1α promoter. This dual-labeling approach allows researchers to distinguish between targeted signaling modulation and fluctuations in cell number or metabolic health. The reporters are stably integrated into the genome, ensuring consistent expression and reliable performance across continuous passages in various experimental conditions.

This cell line serves as a high-performance platform for pharmaceutical screening, particularly in the identification of novel anti-inflammatory compounds and inhibitors of the NF-κB signaling cascade. Because NF-κB is a central regulator of tumor cell survival and immune evasion, the T24-derived model is frequently used to study the molecular drivers of bladder cancer progression and resistance to chemotherapy. In addition to drug discovery, the cell line is valuable for evaluating the pro-inflammatory potential of environmental toxins and assessing the bioactivity of immunomodulatory cytokines like TNF-α. The integration of mCherry enables live-cell imaging and flow cytometry-based analysis, providing a secondary layer of data to verify cell viability during luciferase-based assays. This combined functionality streamlines the validation of therapeutic targets and enhances the accuracy of signal transduction research in both basic oncology and preclinical development.
