Mycobacterial pathogenic strategies remain poorly understood. The slow growth rate of most species, the impenetrable nature of the cell-wall, and the hazards of working with pathogens make mycobacteria difficult to study and are largely responsible for our poor understanding of these organisms. In this video we will demonstrate the technique of electroporation, which involves subjecting cells to a brief high electrical impulse to allow the entry of DNA. It is the most widely used method for...

In utero electroporation is an important technique for studying the molecular mechanisms that guide the proliferation, differentiation, migration, and maturation of cells during neural development. Electroporation enables the rapid and targeted delivery of material into cells by utilizing electrical pulses to create transient pores in cell membranes. Although electroporation has traditionally been used in in vitro studies, scientific advancements have now broadened its utilization to intact...

Bacterial Transformation: Electroporation
0 Views •
2023
The term “transformation” refers cellular ingestion of foreign DNA. In nature, transformation can occur in certain types of bacteria. In molecular biology, however, transformation is artificially induced through the creation of pores in the bacterial cell walls. Bacterial cells that are able to take up DNA from the environment are called competent cells. Electrocompetent cells can be produced in the laboratory and transformation of these cells can be achieve via the application of an...

Craniofacial cartilages develop in close contact with other tissues and are difficult to manipulate in live animals. We are using electroporation to deliver molecular tools during growth of the craniofacial skeleton while bypassing early embryonic effects. This approach will allow us to efficiently test candidate molecules in vivo.

In ovo Electroporation of Chicken Embryos

Electroporation is a technique used in biomedical research that allows for the manipulation of gene expression via the delivery of foreign genetic material into cells. More specifically, in ovo electroporation is performed on early developing chicks (Gallus gallus domesticus) contained within their eggshells. In this procedure, DNA or knockdown constructs are first injected into a target tissue. However, the genetic material is unable to penetrate the plasma membrane to carry out its function...
FAQs
A sufficiently strong electrical pulse raises the cell’s transmembrane potential beyond a critical level. This change produces short-lived pores that increase membrane permeability, allowing selected molecules to cross the membrane. Because the pores are temporary, parameter choices must support molecular entry without driving the membrane toward irreversible damage and the associated loss of cell viability.
Pulse amplitude, duration, number, waveform, and interval collectively shape the balance between membrane permeability and survival. Increasing or changing these settings can alter how effectively molecules enter cells, while unsuitable combinations may increase membrane damage. Researchers therefore consider the full electrical profile rather than treating a single setting as the sole determinant of experimental outcome.
Electrical settings do not operate independently of the biological sample. Cell type, molecule concentration, and buffer composition influence how the system responds to a pulse and therefore must be considered with the electrical parameters. Accounting for these variables helps researchers optimize delivery for a particular experiment instead of assuming that one parameter combination will produce the same outcome across samples.
The central optimization goal is to obtain sufficient membrane permeability for molecular uptake while limiting irreversible membrane damage. Researchers adjust pulse characteristics together with sample conditions, then prioritize settings that support both delivery and survival. This balance matters because a high uptake outcome alone may not provide a useful biological result if excessive damage reduces the viability of the treated cells.
Begin by selecting the molecule to be delivered and considering the target cell type, molecule concentration, and buffer composition. Apply an electrical setting defined by amplitude, duration, number, waveform, and interval, then compare molecular uptake with cell survival. Iterative adjustment of these variables can identify conditions that improve delivery while supporting reproducible experimental results.
Electroporation parameters can be adjusted for delivery of DNA, RNA, proteins, and other biomolecules. In biology, this supports gene delivery, bacterial transformation, and related delivery experiments. The appropriate settings depend on the sample and cargo, so application-specific optimization is important for achieving uptake without compromising the viability needed for subsequent analysis.
Small changes in electrical settings or associated sample conditions can change membrane permeability, molecular uptake, and cell survival. Recording and controlling amplitude, duration, number, waveform, interval, cell type, molecule concentration, and buffer composition gives experimental designs a defined basis for comparison. Careful parameter selection therefore helps researchers reproduce transfection and interpret delivery outcomes more consistently.
