Summary
Phosphate-buffered saline (PBS) offers an economical and effective method for gene delivery in primary endothelial cells using nucleofection. This approach achieves high transfection efficiency and gene knockdown, overcoming the cost barriers of current technologies.
Area of Science:
- Molecular Biology
- Cell Biology
- Biotechnology
Background:
- Nonviral transfection methods for in vitro gene delivery in primary endothelial cells face challenges including cell toxicity, low efficiency, and high costs.
- Novel nucleofection technology offers high transfection efficiency and cell viability but is limited by its high cost, hindering widespread adoption by researchers.
Purpose of the Study:
- To investigate the efficacy of a phosphate-buffered saline (PBS)-based nucleofection method as an economical alternative for gene delivery.
- To compare the transfection efficiency and cell viability of PBS-based nucleofection with commercial buffers in various primary and nonprimary cells.
Main Methods:
- Nucleofection was performed using a novel electroporation condition and buffer components.
- Phosphate-buffered saline (PBS) was utilized as a cost-effective buffer alternative.
- Transfection efficiency and cell viability were comparatively analyzed across different types of primary endothelial cells (arterial, venous, microvascular, lymphatic) and nonprimary cells.
Main Results:
- PBS-based nucleofection demonstrated remarkable transfection efficiency comparable to commercial buffers in both primary and nonprimary cells.
- PBS-mediated nucleofection of small interfering RNA (siRNA) resulted in over 90% knockdown of target gene expression in primary endothelial cells.
- The PBS method proved to be a cost-effective solution for efficient gene delivery.
Conclusions:
- Phosphate-buffered saline (PBS) serves as an effective and economical buffer for nucleofection, enabling efficient gene delivery into diverse cell types, including primary endothelial cells.
- This PBS-based nucleofection method significantly reduces the cost associated with advanced gene delivery techniques, making them more accessible for research.
