NEB 5-alpha Competent E.coli (High Efficiency) C2987U 1 piece

The most common competent cells for cloning. This is a derivative of DH5α. Ideal for general cloning applications. High transformation efficiency (1-3 x 109 cfu/ug pUC19) Blue/white screening is possible. This is an endA1-deficient strain that can prepare high-quality plasmids. This is a recA1 deletion strain that reduces homologous recombination of cloned DNA. Transformation is possible using the 5-minute protocol. Competent cells for cloning Capacity: 96 x 50 μl/tube (12 x 8-tube strips) Genotype: fhuA2 Δ(argF-lacZ)U169 phoA glnV44 Φ80 Δ(lacZ)M15 gyrA96 recA1 relA1 endA1 thi-1 hsdR17 Transformation efficiency: 1-3 x 109 cfu/μg pUC19 DNA Drug resistance: None Click here for the product page.
