Background:

• Transient transfection is crucial in biomedical research but challenging for hard-to-transfect cell lines.
• Existing protocols often fail for cells with atypical morphologies, like mouse pluripotent stem cells in 2i/LIF media.

Purpose of the Study:

• To develop an optimized, rapid reverse transfection protocol for mouse pluripotent stem cells.
• To enhance transfection efficiency and enable efficient poly-transfection for genetic circuit studies.

Main Methods:

• A rapid reverse transfection protocol was optimized for mouse pluripotent stem cells cultured in 2i/LIF media.
• A three-plasmid poly-transfection was performed to explore plasmid stoichiometry.
• A one-pot method was utilized for optimizing plasmid ratios in a single well.

Main Results:

• The optimized protocol achieved higher transfection efficiency in mouse pluripotent stem cells.
• The method facilitated efficient three-plasmid poly-transfection, allowing for expanded study of plasmid stoichiometry.
• The one-pot approach streamlined the optimization of DNA ratios for genetic circuits.

Conclusions:

• This reverse transfection protocol offers a significant improvement for transfecting challenging cell lines like mouse pluripotent stem cells.
• The method accelerates the exploration of DNA stoichiometry effects on genetic circuit function.
• This approach reduces the time and cost associated with embryonic stem cell transfection.
