IL6pro-Luc/EF1α-mCherry Reporter Cell Line - HEK293

IL6pro-Luc/EF1α-mCherry Reporter Cell Line - HEK293 is a genetically engineered human embryonic kidney 293 cell line designed for sensitive monitoring of interleukin-6 (IL-6) promoter activity. The reporter construct contains a firefly luciferase gene driven by the human IL6 promoter, enabling quantitative detection of transcriptional activation through luminescence measurement. In parallel, mCherry is constitutively expressed under the EF1α promoter, providing a stable red fluorescent marker for cell identification, culture monitoring, and normalization of cell number or transfection-related variability. HEK293 cells offer robust growth, high transfection efficiency, and convenient handling, making this reporter line suitable for routine cell-based assays. Upon stimulation with inflammatory signals that activate IL6 transcription, luciferase expression increases and generates a measurable luminescent response.

This reporter cell line is particularly useful for studying inflammatory signaling pathways regulated by IL-6—including the interplay between NF-κB, MAPK, and JAK/STAT pathways, as well as other mechanisms involved in responses to stress or cytokines. It can be employed in compound screening to identify inhibitors or activators of IL-6 promoter activity, and to evaluate the potency and mechanisms of action of anti-inflammatory drug candidates. Furthermore, this cell line can be used to assess the functional effects of various cytokines, pathogen-associated molecular patterns (PAMPs), receptor agonists, and gene-editing reagents that influence IL-6 transcription.
