Specifications

DescriptionGT115 strain is an Escherichia coli strain specially used to clone gene sequences containing DNA secondary structures such as hairpin structures or repeat sequences.
Gene TypesF- mcrA∆ (mrr-hsdRMS-mcrBC) f80lacZDM15∆lacX74 recA1 rpsL (StrR) endA1 ∆dcm uidA (DMluI)::pir-116∆sbcC-sbcD
Size50 µL/vial
QC resultTransformation efficiency of pUC19 plasmid detection:> 1×1010 cfu/μg DNA
Note1. When adding DNA, the volume should not be greater than 1/10 of the competent volume.
2. When adding competitive cells into the electric shock cup, avoid generating air bubbles, which will increase the risk of arc discharge.
3. When the DNA is impure or contaminated with salt, ethanol, protein and buffer, the transformation efficiency drops sharply.
4. The ions in the shock cup can increase the conductance of the solution, increasing the risk of electric current and arcing in solutions containing cells and DNA.
5. If you want to transform large plasmids or want to obtain higher transformation efficiency, it is recommended to use a high-purity plasmid extraction kit to extract the plasmids. Double the size of the plasmid, and the transformation efficiency drops by an order of magnitude.
6. For the transformation of ligation products, the ligation system or recombination system of some companies (for example: Thermo, NEB's T4 ligase system, NEB, Tiangen's 50-degree reaction recombination system) can be directly mixed with GT115 electric shock competent Transformation without purification, but the DNA concentration should not be too high, try not to exceed 100 ng/μl. Too high a concentration of ligation product or too large a volume of ligation product will reduce conversion efficiency and increase the risk of arcing.
7. Gently operate when mixing plasmids, avoid excessive force when sucking competitive cells, so as not to damage the cell membrane due to excessive shearing force and reduce the transformation efficiency. Transforming high concentrations of plasmids or ligation products can correspondingly reduce the amount of bacteria that are ultimately used for plating.
8. Electroporation of competitive cells should be kept below -80°C as much as possible. Over-storage at temperatures above -80°C will cause the transformation efficiency to decrease.
