Electroporation parameters

These results demonstrate that electroporation parameters such as amperage, lag time, and the number of pulses are able to regulate the levels of reporter gene expression in pigs. Publication type Electroporation-based applications require the use of specific pulse parameters for a successful outcome. When recommended values of pulse parameters cannot be set, similar outcomes can be obtained by using equivalent pulse parameters. We determined the relations between the amplitude and duration/number of pulses resulting in the same fraction of electroporated cells. Pulse duration was varied from 150 ns to 100 ms, and the number of pulses from 1 to 128. Fura 2-AM was used to determine. of electroporation parameters Electroporation and electrofusion processes are replacing the chemical methods traditionally used for cell transformation and cell fusion.

  1. Understanding the phenomenon of electroporation, its mechanisms and optimization of all the parameters that affect electroporation is a prerequisite for successful treatment. In addition to the parameters mentioned above, different biological characteristics of treated cell affect the outcome of the treatment. Electroporation, gene electrotransfer and electrofusion are affected by cell membrane fluidity, cytoskeleton, and the presence of the cell wall in bacteria yeast and plant.
  2. Electroporation-the use of high-voltage electric shocks to introduce DNA into cells-can be used with most cell types, yields a high frequency of both stable transformation and transient gene expression and, because it requires fewer steps, can be easier than alternate techniques
  3. Electroporation is a physical transfection method that uses an electrical pulse to create temporary pores in cell membranes through which substances like nucleic acids can pass into cells. It is a highly efficient strategy for the introduction of foreign nucleic acids into many cell types, including bacteria and mammalian cells

The term reversible electroporation refers to non-permanent pore formation when a low-intensity electric field that does not exceed the target tissue's threshold is applied. On the other hand, irreversible electroporation refers to the creation of permanent pores when the electrical field exceeds the target tissue's threshold. These permanent pores lead to cell content leakage, culminating in. Next, we explored different electroporation parameters for both bovine and porcine zygotes to optimize embryo survival rates.
