The dual wave all-around electroporation instrument reshapes cell transfection efficiency through a dual frequency synergistic mechanism, mainly reflected in the intelligent switching between square waves and exponential waves, dynamic regulation of cell membrane permeability, and reduction of cell damage. The following is an introduction:
Intelligent switching between square wave and exponential wave
The innovative integration of dual wave synergistic technology in the dual wave all-around electroporation instrument can accurately match the appropriate combination of square waves and exponential waves based on the membrane structure characteristics of prokaryotic cells (such as Escherichia coli) or eukaryotic cells. For example, when dealing with Escherichia coli, square wave pulses quickly establish a transmembrane electric field to induce membrane pore formation, while exponential wave pulses continuously optimize the electric field distribution, promote the directional migration of plasmid DNA to the cytoplasm, and avoid irreversible damage to the cell membrane that may be caused by a single square wave. This intelligent switching method can more effectively improve the permeability of the cell membrane, making it easier for exogenous DNA to enter the cell, thereby significantly enhancing the conversion efficiency.
Dynamic regulation of cell membrane permeability
Adapting to changes in membrane potential during different cell cycles: Cells undergo changes in membrane potential during different cycles, which can affect the effectiveness of electroporation. The dual frequency synergistic mechanism of the dual wave all-around electroporation instrument can dynamically adjust the parameters of square wave and exponential wave according to the changes in cell cycle membrane potential, ensuring the best electroporation effect in different cell cycles and improving transfection efficiency.
Accurate matching of cell types: Different cell types have different membrane structures and characteristics, and require different parameters for electroporation. The dual wave all-around electroporation instrument is equipped with a database of over 200 cell lines, including commonly used prokaryotic expression hosts such as Escherichia coli and Salmonella, as well as optimization programs for commonly used bacterial, fungal, and mammalian cell lines. Through an intelligent pre optimization system, parameter prediction of new strains can be quickly completed, and dual wave parameters can be accurately matched for different cell types to achieve efficient transfection.
Reduce cell damage and improve cell survival rate
Avoiding energy accumulation and abnormal discharge: Traditional electroporation techniques may have issues with energy accumulation and abnormal discharge, leading to significant cell damage. The dual wave all-around electroporation instrument is equipped with an arc protection system, such as the arc protection 3.0 system, which can monitor pulse energy fluctuations in real time, control the probability of electric spark occurrence at an extremely low level (such as below 0.1%), effectively protect the membrane integrity of competent cells, and reduce cell death during the transformation process.
Shortening membrane repair time: The dual wave synergistic mechanism can also shorten the repair time of cell membranes. During the process of electroporation, pores will form on the cell membrane, which require a certain amount of time for repair. The dual wave all-around electroporation instrument optimizes pulse parameters to complete cell membrane repair in a shorter period of time, thereby maintaining cell activity and function and improving transfection efficiency.
