Lentiviral vectors are widely used for gene delivery, but many laboratories experience challenges such as low transduction efficiency, reduced cell viability, or inconsistent results.
Common Issues
- Low transduction efficiency
- Reduced cell viability
- Poor batch-to-batch reproducibility
- Incorrect MOI selection
Possible Causes
- Inaccurate lentivirus quantification
- Suboptimal MOI
- Poor target cell health
- Improper vector storage or handling
How to Improve Results
Improvement usually starts with accurate titer determination, optimized cell preparation, a validated transduction workflow, and the use of appropriate experimental controls.
