What a Difference a Strain Makes...
Novagen® competent cells include the widest variety of protein expression strains available, as well as both fundamental and advanced strains for cloning applications. Whether you have a “well-behaved” recombinant protein or are facing challenges with truncation, insolubility, or toxicity….whether you need a trustworthy strain for routine cloning or a specialized strain for efficient library construction…our cells can move your research forward.
Since reliability is critical, we verify the phenotype and purity of each strain and guarantee its transformation efficiency. With nearly two decades of experience producing competent cells for protein and molecular biology research, you can count on robust performance.
First introduced in 1990, the Novagen BL21(DE3) strain still sets the GOLD standard for protein expression.
