Protocol describes a method for in ovo transfection of avian embryos with double-stranded RNA (dsRNA). The dsRNA is injected into the spinal cord of the embryo. Subsequent electroporation facilitates the cellular uptake of the dsRNA molecules. - [Read Injection of dsRNA and Electroporation in Avian Embryos Protocol]
Protocol describes a method for in ovo transfection of avian embryos with double-stranded RNA (dsRNA). The dsRNA is injected into the spinal cord of the embryo. Subsequent electroporation facilitates the cellular uptake of the dsRNA molecules. It may be necessary to optimize the stage of the embryo and the electroporation procedure to improve the effectiveness of in ovo RNAi—cell competence changes with differentiation. - [Read Injection of dsRNA and Electroporation in Avian Embryos Protocol]
Protocol describes transfection of plasmid DNA into mammalian cell lines using electroporation, a process whereby external application of electric pulses induce cell membrane permeability. Cells in suspension and small volume cells are difficult to transfect, whereas adherent cells and large volume cells are relatively easy. Regardless of cell size or phenotype, transfection efficiency increases with a high concentration of cells in a small volume. - [Read Optimizing Electrotransfection of Mammalian Cells In Vitro Protocol]
Protocol describes transfection of plasmid DNA into mammaliancell lines using electroporation, a process whereby externalapplication of electric pulses induce cell membrane permeability.A number of factors can affect electrotransfection efficiency.In general, cells in suspension and small volume cells are difficultto transfect, whereas adherent cells and large volume cellsare relatively easy. - [Read Optimizing Electrotransfection of Mammalian Cells In Vitro Protocol]
Protocol describes a method for introducing gene constructsinto mouse embryos by electroporation. Gene constructs can bequickly tested for tissue-specific transcriptional activityor can be used to overexpress gene products. - [Read Protocol Electroporation]
Protocol describes a method for transforming Agrobacterium with plasmid DNA using electroporation in a manner similar to that commonly used for Escherichia coli. Although the transformation efficiency for Agrobacterium is lower than that for E. coli, it is possible to obtain adequate numbers of Agrobacterium transformants with this technique. - [Read Transformation of Agrobacterium Using Electroporation Protocol]
Electrocompetent bacteria are prepared by growing cultures tomid-log phase, washing the bacteria extensively at low temperature,and then resuspending them in a solution of low ionic strengthcontaining glycerol. DNA is introduced during exposure of thebacteria to a short high-voltage electrical discharge.
Protocol describes a method for transformation of the Tetrahymena using electroporation. The vector is electroporated into cells after mating, where it is incorporated into the DNA of developing macronuclei. Because T. thermophila can be propagated indefinitely without conjugation, transformation of the macronucleus provides a way to obtain stable somatic transformants. DNA vectors transformed using this protocol include those containing drug-resistant versions of Tetrahymena genes. - [Read Transformation of Tetrahymena thermophila by Electroporation Protocol]

This protocol a protocol on how to generate transfected embryonic stem (ES) cell clones. The previous protocol in this series is the Protocol for Electroporation of ES cells. The next protocol in the series is the Protocol on Disaggregation, Expansion, and Freezing of Transfected ES Clones.
This protocol describes the electroporation of the BMH 81-17 mut S strain that is recommended for tranformation of the site directed mutagenesis of dsDNA (See Protocol on Site-Directed Mutagenesis on Double Stranded DNA). BMH 81-17 mut S are a mismatch repair defective (mut S) Escherichia coli strain. The probability that the two mutations will cosegregate during the first round of DNA replication is increased in this strain.
