Apheon Bioscience’s DH5-alpha electrocompetent cells are optimized for high efficiency transformations. Cells are ideal for transformations of routine cloning where high numbers of transformants are desired. The DH5-alpha  genotype is similar to other commonly used 5-alpha competent cells offering blue/white selection on agar plates containing X-gal. They also provide high yield and high quality plasmid DNA for subsequent experiments.  For DNA library construction we recommend Aphe 10B Electro-competent cells as they tend to have slightly higher efficiencies.
