Abstract
A new quickly replaceable electrode assembly for electroporation that also provides the functions of a pipette, capable of sucking up samples; applying extremely high electric field strength to samples at lower, safer voltages due to close spacing of the electrode plates; and expelling samples quickly and completely; along with a quick-connect receptacle for the electrode assembly. New methods are detailed for construction of electrode assemblies, providing electric current, monitoring characteristics of electric pulses delivered to samples, and space saving hand held units using low voltage D.C., A.C. line, and piezoelectric power supplies, with peak current delivered indicators are disclosed.
