NEB’s Competent Cells
For your Cloning & Protein Expression
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.

Protein Expression Strains

NEB offers a wide variety of competent cell strains ideal for many protein expression applications. These strains address the needs of protein expression control, toxic protein expression, cytoplasmic disulfide bond formation and difficult targets.
