NEB's competent cells include several popular strains for cloning. Our cloning strains include derivatives of the industry standards, DH5⍺™ and DH10β™. NEB Turbo is unique to NEB and allows colony growth after 6.5 hours. NEB's dam-/dcm-strain enables Dam and Dcm methylation-free plasmid growth. NEB Stable is recommended in all difficult cloning experiments. Our cells are all extensively tested for phage resistance, antibiotic resistance and sensitivity, blue/white screening and transformation efficiency. High efficiency, 5 minute transformation and electroportation protocols are provided, when applicable.
