Protein Expression Products

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.
