CVX5α™ Chemically Competent Cells
Versatile, Convenient & Cost-effective solution for routine Subcloning Procedures
CVX5α™ Chemically Competent Cells is a versatile, convenient and cost-effective solution for routine subcloning procedures or any application where the starting DNA is not limiting. It is calcium chloride-treated to facilitate attachment of the plasmid DNA to the competent cell membrane.
CVX5α™ Genotype: F – , gyrA96, recA1, endA1, thi1, hsdR17 (rK – mK +), deoR, supE44, ∆ (lacZYA-argF) U169 φ80lacZ∆M15 (similar to DH5™ ).Quote request

CVX5α™ Genotype: F – , gyrA96, recA1, endA1, thi1, hsdR17 (rK – mK +), deoR, supE44, ∆ (lacZYA-argF) U169 φ80lacZ∆M15 (similar to DH5™ ).
Includes for 40 rxn:
– 2,000 µL CVX5α™ (1 x 107 CFU/µg)
– 10 µL pUC18 Transformation Control Plasmid (10 ng/µL)
– 50 mL SOC Medium
– Dry ice
- Routine cloning and subcloning of genes into plasmid vectors.
- Each lot of competent cells is tested to verify transformation efficiencies using 100 pg pUC18 supercoiled DNA and the recommended protocol.
- Under these conditions, transformation efficiency will be ≥ 1 x 107 cfu/μg pUC18.
- Transformation efficiency is defined as the number of colony forming units (cfu) produced by transforming 1 μg of plasmid (3 kb) into a given volume of competent cells.
- Note: Optimal competence for cloning but it is not enough for the generation of cDNA libraries.
Storage, Shipping & Guarantee
- Shipped in: Dry ice.
- Storage: Upon receipt, store cells immediately at -80 °C.
- Recommendations: Storage at -20 °C will result in a significant decrease in transformation efficiency. Please note that competent cells are very sensitive to cycles of freezing and thawing and should not be exposed to temperature variations
- Guaranteed: 12 months from the date of purchase, if it is properly stored.
