Useful for Agrobacterium-mediated genetic transformation of Arabidopsis thaliana, tobacco, corn, potato, and other plants.
GV3101 ElectroCompetent Agrobacterium
$285.00 – $495.00
Intact Genomics GV3101 ElectroCompetent Agrobacterium cells are optimized for the highest transformation efficiencies which is ideal for applications requiring high transformation efficiencies, such as with cDNA or gDNA library construction.
The GV3101 strain contains T-DNA located in its own Ti-plasmid making it capable of integration into plant chromosomal DNA. Therefore, it is used for Agrobacterium-mediated genetic transformation of Arabidopsis thaliana, tobacco, corn, potato, and other plants.
Competent cell type: Electrocompetent
Species: A. tumefaciens
Transformation efficiency: ≥ 1 x 107 cfu/µg pCAMBIA1391z DNA
Blue/white screening: No
Shipping condition: Dry ice
Reagents Needed for One Reaction
GV3101 ElectroComp Agrobacterium: 25 µl
DNA (pCAMBIA1391z, 500 pg/µl): 1 µl
Recovery medium: 1 ml
GV3101 ElectroComp Agrobacterium: -80 ºC
pCAMBIA1391z control DNA: -20 ºC
Recovery medium: 4 ºC
Transformation efficiency is tested by using the pCAMBIA1391z control DNA supplied with the kit and using the protocol in this manual. Transformation efficiency should be ≥1 x 107 CFU/µg pCAMBIA1391z DNA. Untransformed cells are tested for appropriate antibiotic sensitivity.1282-12 1282-24
Use this procedure to transform GV3101 ElectroComp Agrobacterium. Do not use these cells for chemically transformation.
1) Place sterile cuvettes and microcentrifuge tubes on ice.
2) Remove competent cells from the -80 °C freezer and thaw completely on wet ice (10-15 minutes).
3) Aliquot 1 µl ( 10pg -1 µg) of DNA to the chilled microcentrifuge tubes on ice.
4) When the cells are thawed, add 25 μl of cells to each DNA tube on ice and mix gently by tapping 4-5 times. For the pCAMBIA1391z control, add 1 µl of (500 pg/µl) DNA to the 25 µl of cells on ice. Mix well by tapping. Do not pipette up and down or vortex to mix, this can harm cells and decrease transformation efficiency.
5) Pipette 26 µl of the cell/DNA mixture into a chilled electroporation cuvette without introducing bubbles. Quickly flick the cuvette downward with your wrist to deposit the cells across the bottom of the well and then electroporate.
6) Immediately add 976 µl of Recovery Medium or any other medium of choice to the cuvette, pipette up and down three times to re-suspend the cells. Transfer the cells and Recovery Medium to an Eppendorf tube.
7) Incubate tubes at 30 °C for 3 hours at 200 RPM.
8) Dilute the cells as appropriate then spread 20-200 μl cells onto a pre-warmed selective plate. For the pCAMBIA1391z control, you may plate 50 μl of diluted transformants onto a YT plate containing 30 μg/ml gentamycin and 50 μg/ml kanamycin. Use sterilized spreader or autoclaved ColiRoller™ plating beads to spread evenly.
9) Incubate the plates for 2 – 3 days at 30 °C.
