Electroporation is a non-viral transfection method that applies an electric pulse to cells to cause transient permeability in the cell membrane. Diverse genetic engineering payloads such as DNA, mRNA, CRISPR, sgRNA and RNPs can travel through the membrane and enter the cell. Electroporation is a highly efficient delivery method that can be applied to a variety of cell types, from insect to mammalian.
How does Electroporation Work?
Electroporation is a straightforward process. Your cells and genetic engineering molecules of choice are suspended in a conductive solution and placed inside a processing assembly. Electrodes deliver an electric pulse across the solution following a protocol optimized for voltage and duration depending on cell type.
Optimizations and Innovations
Numerous parameters can be optimized when performing electroporation to ensure high viability and efficient delivery. At MaxCyte® we have spent 20 years refining our approach to electroporation and we would love to share what we’ve learned.
Salts are commonly added to buffers to adjust conductivity. Osmolarity, however, affects cell membrane permeability and cell viability and must be adjusted by adding inert proteins or sugars.
At MaxCyte, we’ve taken the hard work out of buffer optimization by designing a solution that works with all cell types and is tailored to work with our instruments and protocols.
Achieving successful transfection by applying an electric pulse requires precision. The strength, duration and number of pulses used to permeabilize membranes must be calibrated to the specific cell. That’s why MaxCyte has developed over 100 protocols for diverse cell types. With us, selecting the right electroporation protocol is as simple as the touch of a button.
An overlooked aspect of electroporation optimization is the design of the processing chamber. At MaxCyte we have developed specialized processing assemblies with inert materials to prevent biological and chemical contamination. Our electrodes are made of clinical-grade materials chosen to prevent toxic metal ions from forming in the cell suspension. Our processing assemblies ensure electroporation is gentle on cells without affecting phenotype and viability.
