Electroporation, or electropermeabilization, is a significant increase in the electrical conductivity and permeability of the cell plasma membrane caused by an externally applied electrical field. It is usually used in molecular Biology as a way of introducing some substance into a cell, such as loading it with a molecular probe, a drug that can change the cell's function, or a piece of coding DNA.

How electroporation increase permeability of plasma membrane?
Electroporation is a dynamic phenomenon that depends on the local transmembrane voltage at each point on the cell membrane. It is generally accepted that for a given pulse duration and shape, a specific transmembrane voltage threshold exists for the manifestation of the electroporation phenomenon (from 0.5 V to 1 V). This leads to the definition of an electric field magnitude threshold for electroporation (Eth). That is, only the cells within areas where E≧Eth are electroporated. If a second threshold (Eir) is reached or surpassed, electroporation will compromise the viability of the cells, i.e., irreversible electroporation.[2]
What kind of technology is electroporation?
Electroporation is the technology that is connected to the increase of electrical conductivity that is seen in the cell. This can cause the cell membrane to weaken and be more easily punctured.

5 ways of getting DNA into a cell?
Gene gun, transformation, electroporation, protoplast fusion and microinjection.
Can E Coli be transformed?
I don`t know other ways but I know that It can be transformed chemically & by electroporation
How are genes transfered?
gene transferring methods includes: gene gun method, biopsy, electroporation, biolistics, cloning vectors.
How is electropitation done?
No such word in the dictionary or encyclopedia. There is the word electroporation that refers to electrical pulses used to create temporary pores in cell membranes.
How bt corn is made?
Bt corn is made by introducing vector plasmids into agrobacterium by electroporation. Electroporation is the creation of transporent pores in the membrane of a cell, through the application of a high-voltage electrical pulse.
Where is it proven that Robert C Beck DSc physics' biocompatible electric current applied to bodily tissues-blood electrification etc is not low-power electroporation-EP similar to drug delivery EP?
(Source- http:/www.toolsforhealing.com/CD/Articles/Q/QuestionsAnswersabouttheB.html - as posted by Michael Forrest on January 11, 1998) From Brian Austin, Technical Support Manager at Genetronics (an electroporation device company), "with the (electrical) conditions use (by Bob Beck's Black Box), there should be no electroporation effects. Field strengths are not high enough." From J. C. Weaver of Massachusetts Institute of Technology in his report on electroporation published in the Journal of Cellular Biochemistry (51:426-435 1993) reported "In the case of isolated cells, mammalian cells experience electroporation for electric fields of about E=1kv/cm (1000 volts with a distance of 1 centimeter between electrodes) for short pulses." The Black Box produces about 1.35 volts per centimeter when the electrodes are placed on the same wrist. From another electroporation device manufacturer, Cyto Pulse Sciences, stated on their website (in the equipment tutorial) that red blood cells need 1430 volts per centimeter for electroporation. However, there is evidence that blood cells are more absoptive during electricfication in the Biophysics Journal, Vol. 58 Oct 1990, pages 897-903 where the authors wrote "...electric fields that generate transmembrane potential in the range of millivolts are capable of activating membrane transport systems." (The Black Box creates a potential across the blood cell membranes of millivolts.) Also;"...reversible activation of certain membrane channels or transport systems may be achieved using low-amplitude, low frequency alternating current fields. Electric fields as small as 16 volts per centimeter have been shown to induce membrane conductance , and these effects were completely reversible. Human erythrocytes treated with such ac fields for hours were shown to have normal shape, volume, and permeabilities to potassium and sodium."
