EF1a FLuc Reporter Lentivirus

The EF1a FLuc reporter lentivirus is a highly efficient gene delivery tool designed to stably express firefly luciferase (FLuc) under the control of the human elongation factor 1 alpha (EF1α) promoter. This lentiviral vector utilizes the powerful, constitutive EF1α promoter, ensuring long-term, high-level expression of FLuc in a variety of mammalian cell types, including dividing and non-dividing cells. The viral particles are pseudotyped with the vesicular stomatitis virus glycoprotein (VSV-G), conferring broad tropism and efficient transduction. The FLuc reporter gene integrates into the host genome, enabling sensitive and quantitative monitoring of gene expression dynamics in vitro and in vivo. Safety features such as the self-inactivating (SIN) long terminal repeat (LTR) further reduce the risk of insertional mutagenesis, making it a reliable tool for biomedical research.

The EF1a FLuc reporter lentivirus is widely used in molecular and cellular biology for a variety of applications. In gene therapy research, it is a key tool for tracking the persistence and distribution of transduced cells in animal models using bioluminescence imaging (BLI). In cancer research, the FLuc reporter gene enables non-invasive, real-time monitoring of tumor growth, metastasis, and therapeutic response. In stem cell research, this lentivirus is used to label and track the fate of transplanted stem cells, providing insights into their differentiation and engraftment efficiency. Furthermore, it is widely used in drug screening assays to assess compound efficacy by quantifying changes in FLuc activity as a surrogate marker of cellular response. The constitutive EF1α promoter ensures consistent expression across different cell types, making it ideal for comparative studies in primary cells, immortalized cell lines, and organoids.
