Considerations for Selecting Transfection Reagents in CGT
When choosing transfection reagents for cell and gene therapy applications, consider the following factors:
- Cell Type Specificity: Some reagents are optimized for specific cell types, including primary cells or stem cells.
- Transfection Efficiency: High efficiency is crucial for therapeutic applications to achieve the desired gene expression levels.
- Cytotoxicity: Low toxicity is essential to maintain cell viability, especially when scaling up for clinical applications.
- Scalability: Reagents should be suitable for large-scale manufacturing processes, adhering to Good Manufacturing Practice (GMP) standards.
