CMV GLuc Reporter Lentivirus

The CMV GLuc reporter lentivirus is a highly efficient lentiviral vector genetically engineered to express Gaussia luciferase (GLuc) under the control of the human cytomegalovirus (CMV) promoter. This vector is designed to achieve stable and sustained gene expression in a variety of mammalian cell types, including dividing and non-dividing cells. The lentiviral backbone ensures stable genomic integration, enabling long-term monitoring of gene activity. The Gaussia luciferase reporter gene is a secreted enzyme with exceptional sensitivity (10-1000-fold higher than firefly or Renilla luciferase) and rapid detection kinetics, making it ideal for quantitative analysis. The virus is pseudotyped with the vesicular stomatitis virus glycoprotein (VSV-G), enhancing its tropism and transduction efficiency in various cell types. Additional safety features, such as a self-inactivating (SIN) LTR and a split packaging system, minimize the risk of generating replication-competent virus, thereby ensuring biosafety.

The CMV GLuc reporter lentivirus is widely used in molecular and cellular biology for real-time tracking of gene expression, promoter activity analysis, and high-throughput screening. Its secreted GLuc reporter gene enables non-destructive sampling of cell culture supernatants, facilitating dynamic studies of signaling pathways, drug responses, and transcriptional regulation. In virology and immunology, this tool is used to study host-pathogen interactions or immune cell activation by coupling GLuc secretion to specific stimuli. Furthermore, it serves as a critical component in in vivo imaging, where systemic delivery of the lentivirus enables longitudinal monitoring of gene expression in animal models via bioluminescence assays.
