NEB Cloning Competent E. coli Sampler
Not sure which cloning strain to choose? The NEB Cloning Competent E.coli Sampler allows you to sample 4 of our popular chemically competent strains. The Sampler includes two 0.05 ml tubes of each of the following strains (as well as outgrowth medium and control):
- NEB 5-alpha: Our best-selling strain for basic cloning; Derivative of the popular DH5α. It is T1 phage resistant and endA deficient for high-quality plasmid preparations.
- NEB 10-beta: derivative of the popular DH10B. It is T1 phage resistant and endonuclease I (endA1) deficient for high-quality plasmid preparations.
- NEB Stable: Ideal for isolation of plasmid clones containing repeat elements and unstable inserts. Useful for isolating and propagating retroviral/lentiviral clones
- NEB Turbo: Features fast colony growth (6.5 hours) and tight expression control (lacIq). Isolate DNA after only 4 hours of growth
