Protein Expression

Recombinant production of proteins is one of the most powerful techniques used in the Life Sciences. The ability to produce and purify an abundance of a desired recombinant protein can permit a wide range of possibilities including its use in industrial processes, or its use to diagnose or treat disease.

At first glance, recombinant protein expression may appear simple. Essentially, DNA encoding a target protein is cloned downstream of a promoter in an expression vector. This vector is then introduced into a host cell, and the cell’s protein synthesis machinery produces the desired protein. In practice, however, protein expression can be very challenging because so many factors may influence the process. For example, each protein folds in its own unique manner, a process that may be influenced by the choice of expression host. Similarly, some proteins require post-translational modifications or proper insertion into a biological membrane. Finally, some proteins may have an activity that is detrimental to the host. Thus, no single solution exists for successful production of all recombinant proteins. Instead, it is beneficial to have access to a wide range of expression tools, and a willingness to explore multiple approaches to better one’s chances for success. Protein Expression at NEB.

 
New England Biolabs is committed to providing advanced tools for protein expression. As a leading supplier for reagents in the biotechnology field, NEB understands the importance of convenient and easy-to-use systems for high level expression and purification of proteins. We invite you to review our growing range of expression systems, including our new line of NEBExpress® products, resulting from our 40+ years of experience in cloning, over-expression and purification. We use these solutions in our own research and manufacturing processes, and know that quality and performance are critical – all of our products are stringently tested so that you can be sure they will work optimally for your solution, just as we rely on them to work in ours.
