General information
Champion™ Competent Cells are chemically competent cells, which were prepared by SMOBIO to make E. coli perform excellent transformation efficiency. Standard transformation protocol is recommended for large plasmids or non-ampicillin selection. Time-saving transformation protocol is recommended for simple and rapid transformation. Champion™ Competent Cells are one of the fastest and simplest ready-to-use competent cell products in the world.

Shipping condition
Throughout the shipping process, the temperature is maintained under -70°C.
Storage and expiration
Champion™ Competent Cells must be stored between -70°C to -80°C. Subsequent freeze-thaw cycles will reduce transformation efficiency. If high efficiency is required for the experiment, do not use aliquots that have gone through several freeze-thaw cycles. The efficiency of Champion™ Competent Cells lasts for 1 year with proper storage.

Protocol card
When Champion™ competent cells are thawed dispensed in aliquots and refrozen within 1 min, the transformation efficiency will be 10~20% reduced compared to the first time use.
Using circulating water can reduce the thawing time. Less thawing time shows higher efficiency than long thawing time.
The bending glass rod shows best efficiency and the plating loop show less efficiency than other method. For handle a lot samples at the same time the plating beads are recommended.
One second vortex provides more reliable transformation efficiency (1.1 times compare with mixed by finger tapping)
Heat shock treatment will enhance the efficiency about 1~2X versus non-heat shock method.
Shorter thawing time is more efficient than a longer thawing time. Slow thawing caused by power shortages and unstable freezers will result in decreased efficiency.
Plasmid size affect the efficiency greatly. The efficiency of transforming a supercoiled 2.7 kb is approximately 100 times higher than that of a 10 Kb plasmid (using time-saving transformation protocol). For large plasmids (> 6 kb), standard transformation protocol is recommended.
Heat shock treatment will enhance the efficiency about 1~2 folds versus non-heat shock method.
Bent glass rods show the greatest efficiency, while plating loop shows less efficiency than plating beads. When handling a large quantity of samples at the same time, plating beads are recommended.
Antibiotic concentration is critical to use of the time-saving transformation protocol.
Antibiotic | Concentration |
Ampicillin (Ap) | 20 μg/ml |
Kanamycin (Km) | 25 μg/ml |
Tetracycline (Tc) | 7.5 μg/ml |
Chloramphenicol (Cm) | 20 μg/ml |
For plasmid size <6 Kb, the efficiency of kanamycin selection is usually 3~10 times less than the ampicillin selection. For plasmid size > 6 Kb, the efficiency of kanamycin selection is much lower than ampicillin. We suggest using the standard transformation protocol (with heat shock and recovery steps) to enhance the efficiency.
