Luc Reporter Cell Line - GL261

GL261 is a comprehensively characterized murine glioma cell line, originally induced via the intracranial implantation of 3-methylcholanthrene into a C57BL/6 mouse. Growing as an adherent monolayer with classic glial morphology, GL261 serves as a foundational syngeneic model in neuro-oncology and is particularly highly valued for modeling glioblastoma multiforme (GBM). Because it is fully compatible with immunocompetent C57BL/6 mice, it is an indispensable tool for studying tumor-immune system interactions. The Luc Reporter Cell Line - GL261 advances this critical oncological model through the stable genetic integration and constitutive expression of the firefly luciferase (Luc) reporter gene. This precise genetic engineering enables the cells to produce a robust, highly quantifiable bioluminescent signal upon exposure to the substrate D-luciferin. The engineered reporter cells strictly maintain their native morphology, highly aggressive in vivo growth dynamics, and baseline immunogenic profile, ensuring researchers have access to a biologically authentic and easily traceable in vitro model for advanced brain cancer research.

The constitutive expression of the luciferase reporter transforms the GL261 cell line into an invaluable asset for rigorous in vitro analytics and complex preclinical animal modeling, particularly within the rapidly expanding field of neuro-immuno-oncology. In standard laboratory environments, the luminescent output allows for highly sensitive, high-throughput quantification of cell viability, making it an ideal platform for screening novel chemotherapeutics, targeted targeted pathway inhibitors, and evaluating the in vitro cytotoxicity of engineered immune cells, such as CAR-T or natural killer (NK) cells. The primary advantage of this reporter line is fully realized in advanced in vivo studies. When utilized to establish orthotopic intracranial tumors in immunocompetent mice, the robust luciferase emission enables highly sensitive, non-invasive bioluminescence imaging (BLI).
