For nearly 50 years, NEB has been a world leader in the discovery and production of reagents for the life science industry. Decades of experience in practicing molecular biology has led to the design and manufacture of a broad product portfolio that has the potential to touch almost every stage of today’s biotechnology and therapeutic discovery and development process. Our commitment to product quality and stringent quality control practices means you can be confident our products will work for your application.

To better serve the needs of customers in regulated markets, in 2018 NEB opened a state-of-the-art 43,000 sq. ft. production facility in Rowley, MA for the manufacture of GMP-grade* products – approximately 15 minutes from our main campus in Ipswich, MA. This purpose-built facility includes Quality Control and Production functions ranging from a shipping/receiving area and dedicated warehouse, to separate inoculation preparation, fermentation, purification and fill suites.

Understanding your needs and minimizing risk

NEB's expertise in enzyme manufacturing positions us to best anticipate your needs and minimize the risk of transferring manufacture of your development materials to our GMP-grade production facility. The product attributes that differentiate NEB’s GMP-grade products include:

  • Bioburden and/or endotoxin specifications on products
  • Certified animal-free origin and manufacturing process
  • Qualified equipment, utilities, QC test methods and controlled manufacturing processes to deliver the highest levels of lot-to-lot consistency

NEB’s GMP-grade products are produced in compliance with the ISO 13485:2016 Quality Management Standard, and are also in line with many of the principles defined in U.S. 21 CFR 820 “Quality System Regulation” – Medical Devices.

Not sure whether you need research-grade (RUO) or GMP-grade products?

We are happy to work with you to assess your needs to help identify which solution will work best for you. Our RUO products are highly pure and undergo stringent quality controls, and in many cases, will satisfy your needs. Our GMP-grade products are NEB’s highest quality grade product and are available for your further processing. The table below highlights our capabilities for both RUO and GMP-grade products.

* "GMP-grade" is a branding term NEB uses to describe products manufactured or finished at NEB’s Rowley facility. The Rowley facility was designed to manufacture products under more rigorous infrastructure and process controls to achieve more stringent product specifications and customer requirements. Products manufactured at NEB’s Rowley facility are manufactured in compliance with ISO 9001 and ISO 13485 quality management system standards. However, at this time, NEB does not manufacture or sell products known as Active Pharmaceutical Ingredients (APIs), nor does NEB manufacture its products in compliance with all of the Current Good Manufacturing Practice regulations.
