Competent Cells

Cloning Strains

For cloning experiments choose from several high efficiency competent cell strains. These E. coli strains are T1 phage resistant and are endA deficient for high quality plasmid preparations. Additionally, all competent cells from NEB are free of animal products.

Yeast

NEB offers chemically competent Kluyveromyces lactis cells and variants of this strain that have been tailored for specific protein expression needs. These cells are suitable for transformation with any of our linearized pKLAC series expression vectors.

E. coli for Protein Expression

NEB offers several strains with varying levels of expression control, each with T1 phage resistance and extremely high transformation efficiencies.
