Electroporation
Achieving efficient delivery of gene editing systems into cells is a crucial step for successful gene editing, as delivery efficiency is positively correlated with editing efficiency. Electroporation is a highly efficient delivery method that uses high-voltage electric pulses to create pores in the cell membrane, allowing the introduction of foreign DNA, RNA, or other molecules into the cells. This transfection method can be applied to most cell types and offers advantages such as high transfection efficiency and broad applicability.

Literature Review
Traditional generation of gene-edited animals relies on microinjection of CRISPR/Cas9 proteins and donor DNA into zygotes, a method known for its low efficiency, time-consuming nature, and high technical skill requirements. Remy et al. reported an optimized electroporation method for delivering sgRNA and Cas9 proteins, with or without ssODN (single-stranded DNA fragments), into intact rat zygotes to improve gene-editing efficiency. Using ssODN as the donor template, this approach achieved precise knock-in mutations in 25-100% of the analyzed animals.

FAQ
What issues should be considered when culturing cells for gene delivery?
Maintaining the activity of cell cultures is crucial. Cells should not be allowed to reach confluence for more than 24 hours. Frozen new cells can restore transfection activity. The optimal cell plating density varies for different cell types or applications; however, for adherent cells, a confluence of 70% to 90% or a density of 5×10^5 to 2×10^6 suspended cells/ml typically yields good transfection results. It is important to ensure that cells are not fully confluent or in a fixed phase during transfection.
How to choose the appropriate gene delivery method?
Selecting a suitable gene delivery system requires a comprehensive assessment based on specific experimental conditions, research objectives, and cell types. Quantitatively comparing various systems in terms of delivery efficiency, cytotoxicity, and stability is an important step in determining the choice.
Viral delivery systems are suitable for experiments that require high delivery efficiency and sustained gene expression, especially when cells can tolerate higher levels of cytotoxicity and immune responses. If lower cytotoxicity and immune response, along with ease of use and cost-effectiveness, are priorities, then a liposome-based gene delivery system should be chosen. For high delivery efficiency that involves delivering large DNA fragments, and if the user can accept a higher operational complexity, a gene gun delivery system is an optional method. If high delivery efficiency is needed while maintaining relative simplicity and no special equipment is required, then the electroporation delivery system may be a suitable choice.
