Why Electroporation? Because electroporation is the most popular, most versatile, most efficient transformation method available for gene expression analysis of the widest variety of cell types.

In British medical officer Frederick Griffith conducted a series of classic experiments with colonies of rough- and smooth-coated Streptococcus pneumoniae. These experiments led Griffith to discover the phenomenon of transformation the assimilation of exogenous genetic material by a cell and were an important impetus for subsequent research into the nature of the double helix by Watson and Electroporation efficiently introduces nucleic acids, siRNA duplexes, and other molecules into numerous cell types.

Transiently permeabilized by a square-wave or exponentially pulsed electrical field, cell membranes readily permit exogenous molecules from the surrounding medium to enter the cell. Once inside the cell, these molecules become assimilated into the cellular DNA. Safely and successfully used to introduce DNA, RNA, siRNAs, proteins, virions, nucleotides, carbohydrates, and even dyes into prokaryotic and eukaryotic cells, electroporation provides both an attractive alternative and The system is available in three combinations.

Exponential and Square-Wave Pulses The Gene Pulser Xcell system generates both exponential and square waveforms, enabling you to choose the waveform and protocol that will work best for your cells. Exponential Decay The chosen voltage is released from the capacitors and decays exponentially over time. The field strength is controlled by adjusting the voltage on the Gene Pulser Xcell system for a known electrode distance.
