GoldBio Competent Cells Consistently Exhibit Higher Transformation Efficiencies
DH10B chemically competent E. coli cells and DH10B Electrocompetent E. coli cells exhibit higher transformation efficiency than competitors. Each transformation with DH10B chemically competent E. coli cells was performed using 1 ml of final volume including recovery media, plating 50 μl after a 10 fold-dilution (left). For electrocompetent cell comparison, DH10B Electrocompetent E. coli cells were electroporated using a 1 ml of final volume including recovery media, plating 50 μl after 100-fold dilution (right).

Electroporation and Electrocompetent Cells FAQs:
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.
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.
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 AGL-1 Agrobacterium Electrocompetent Cells are optimized to produce the highest transformation efficiency, and are ideal for applications requiring high transformation efficiencies such as cDNA or gDNA library construction. The AGL-1 strain has a C58 chromosomal background that carries an insertion mutation in its recA recombination gene which stabilizes recombinant plasmids. It also carries rifampicin and carbenicillin resistance in its genome for selection. AGL-1 contains the Ti plasmid pTiBo542 from which the T-DNA region sequences have been deleted. Transformation with a binary vector containing the missing T-region results in a functional T-DNA binary system that allows for transfer of genetic material into a host plant’s genome. Therefore, this system is often used for Agrobacterium-mediated transformation of Arabidopsis thaliana as well as maize and other monocots.

i7® Hot Start High-Fidelity DNA Polymerase 2X Master Mix is ready to use premix which contains hot start i7® high-fidelity DNA Polymerase, dNTPs, MgCl2, PCR enhancers and stabilizers with optimized proprietary reaction buffer. i7® Hot Start High-Fidelity DNA Polymerase is a genetically engineered, heat stable DNA polymerase which has 5´→3´ polymerase and 3´→5´ exonuclease (proofreading) activities. This enzyme has the high-fidelity, sensitivity and processivity with an error rate ~2.8 × 102-fold lower than Taq DNA polymerase, and significantly lower than the error rates of other proofreading enzymes in the marketplace. This 2X master mix product is supplied with 5X GC enhancer that enables efficient amplification of GC rich templates up to 84%.
Applications
- Long and difficult template DNA amplification
- Cloning
- High-fidelity PCR
- Efficient for amplifying high GC content template DNA with GC enhancer.
