Electroporation and Electrocompetent Cells FAQs:
What is electroporation?
Electroporation is a technique commonly used in transformation assays to introduce DNA into an electrocompetent cell. During electroporation a transient current or electrical pulse is applied to cells that have been suspended in a solution. The current momentarily increases the permeability of the cell's membrane, creating holes (a pathway) that allow DNA (plasmids) to pass through and enter the cell. Generally, electroporation can be more effective than chemical transformation.
When should I use electrocompetent cells?
Electrocompetent cells have a higher transformation efficiency than chemically competent cells. The use of electrocompetent cells facilitate the transformation of large plasmids, including BACs (Bacterial Artificial Chromosomes), that might otherwise be difficult to transform using chemical transformation.
How do I prevent arcing during electroporation?
Arcing during electroporation can be avoided by making sure there are no air bubbles in the cell/DNA solution prior to electroporation. Also, desalt your DNA since the presence of conductive ions in the solution will cause arcing and electroporation failure. In addition, ensure that your equipment, including the cuvette is properly cleaned and in good condition.

Description
GoldBio’s EHA105 (pSoup-P19) chemically competent Agrobacterium cells are optimized for high transformation efficiencies, making them ideal for applications such as cDNA or gDNA library construction. These cells are resistant to rifampicin, chloramphenicol, and streptomycin, providing versatility in selection and antibiotic resistance EHA105 strain contains a rifampicin resistance gene (rif) and an amber basic Ti plasmid pEHA105 (pTiBo542DT-DNA) without self-transport function, containing the vir gene.
The pSoup plasmid present in these cells is required for the replication of pGreen, 62SK, and pGs2 series plasmids, increasing the range of applications for the EHA105 (pSoup) system. The p19 protein is derived from tomato bush dwarf virus and further improves the stability of heterologous gene transcripts by inhibiting RNA silencing of foreign. These competent cells are suitable for Agrobacterium-mediated transformation of dicots such as Arabidopsis thaliana, tobacco, potato, as well as monocots like corn, making them an ideal choice for plant molecular biology research.
GoldBio’s EHA105 Agrobacteriumstrain was generated, and primary clone supplied by Dr. Elizabeth Hood.
