EF1a RLuc Reporter Lentivirus

The EF1a RLuc reporter lentivirus is a highly efficient, replication-incompetent viral vector designed for stable gene expression in mammalian cells. This lentiviral vector contains the elongation factor 1 alpha (EF1a) promoter, ensuring robust, constitutive expression of the Renilla luciferase (RLuc) reporter gene in a variety of cell types, including primary and difficult-to-transfect cells. The virus is pseudotyped with the vesicular stomatitis virus glycoprotein (VSV-G), which imparts broad tropism and efficient transduction. The reporter gene integrates into the host genome, enabling long-term monitoring of gene expression, cellular processes, or promoter activity.

The EF1a RLuc reporter lentivirus is a versatile tool widely used in molecular and cellular research. Its primary application is in gene expression studies, where RLuc, a sensitive bioluminescent reporter, can be used to quantify promoter activity or signaling pathways. In drug discovery, monitoring RLuc activity as a functional marker enables high-throughput screening of compounds targeting specific pathways. For cell-based assays, the stable integration of RLuc enables long-term tracking of cell proliferation, apoptosis, or metabolic changes in vitro and in vivo. Furthermore, because RLuc''s low background noise and high signal-to-noise ratio facilitate non-invasive bioluminescence imaging (BLI), this lentivirus is also well-suited for biodistribution and imaging studies in animal models. Its compatibility with primary cells, stem cells, and organoids makes it valuable in disease modeling and therapeutic development.
