Understanding FXR-V5/RFP-BSD Lentivirus AffiLENTI
FXR-V5/RFP-BSD Lentivirus AffiLENTI is a lentiviral vector engineered to express a fusion protein consisting of the FXR (Farnesoid X Receptor) V5 tag, RFP (Red Fluorescent Protein), and BSD (Blasticidin S Deaminase) selection marker. The incorporation of these elements enables efficient transduction, visualization, and selection of target cells.
Materials and Methods
The FXR-V5/RFP-BSD Lentivirus AffiLENTI vector was constructed by cloning the fusion gene consisting of the FXR-V5 epitope tag, the red fluorescent protein (RFP) reporter gene, and the blasticidin S deaminase (BSD) selectable marker into a lentiviral backbone. Vector production was carried out using standard protocols, and viral titers were determined by qPCR. Transduction efficiency was assessed in various cell lines, including HEK 293 and A549 cells, using flow cytometry analysis. Stability of transgene expression was evaluated over multiple passages.
Key Features
FXR Tag
The FXR tag facilitates the tracking and identification of transduced cells, allowing researchers to monitor gene expression and localization in real-time.
RFP Reporter
The RFP reporter gene provides a visible marker for transduced cells, simplifying the detection and quantification of lentiviral transduction efficiency.
BSD Selection Marker
The BSD selection marker confers resistance to blasticidin, enabling the isolation and maintenance of transduced cells through antibiotic selection. This feature is particularly advantageous for stable cell line generation and long-term studies.
Applications
Gene Overexpression and Knockdown Studies
FXR-V5/RFP-BSD Lentivirus AffiLENTI can be utilized to overexpress or knockdown target genes in a wide range of cell types, facilitating functional studies and elucidating gene function.
Cellular Imaging and Tracking

Cell Line Establishment
The BSD selection marker enables the generation of stable cell lines with sustained gene expression, providing a valuable resource for cell-based assays and screening studies.
Experimental Considerations
Transduction Efficiency
Optimal transduction efficiency can be achieved by titrating viral particle concentration and optimizing transduction conditions according to the target cell type.
Selection Pressure
Proper selection pressure must be applied to ensure the survival and proliferation of transduced cells during antibiotic selection using blasticidin.
Validation of Transgene Expression
Verification of transgene expression and functionality is essential through techniques such as immunofluorescence, Western blotting, or functional assays, depending on the experimental requirements.
In conclusion FXR-V5/RFP-BSD Lentivirus AffiLENTI represents a powerful tool for genetic manipulation and cellular studies, offering efficient gene delivery, visualization, and selection capabilities.
