New Protein A Chromatography Resin Increases Monoclonal Antibody Purification by up to 40%

GE Healthcare introduces a new Protein A chromatography resin, MabSelect PrismA, which will help biopharmaceutical manufacturers improve their monoclonal antibody (mAb) purification capacity by up to 40%. The resin is also significantly more alkaline-stable, meaning that MabSelect PrismA can be cleaned with a higher concentration of sodium hydroxide to better control cross-contamination and bioburden risks.

MabSelect PrismA addresses a number of key challenges, including the increased upstream titers. The new resin is highly efficient due to its excellent binding capacity, which is critical, because it determines how much resin is needed to purify a certain amount of protein.

“Biopharma companies are constantly looking for more ways to increase their output, and Protein A has a critical role to support these efforts. The thorough research and development work that we have carried out to create MabSelect PrismA sets a new standard for mAb purification. To put it simply, with this chromatography resin our customers will be able to produce more biopharmaceuticals out of their existing manufacturing equipment. Protein purification is no longer a bottleneck, but driving higher productivity and shorter manufacturing lead times for our customers,” said Jan Makela, General Manager, BioProcess, GE Healthcare Life Sciences.

MabSelect PrismA has been developed at the GE Healthcare Life Sciences site in Uppsala, Sweden, where the resin is also manufactured. The factory in Uppsala is one of the largest manufacturing facilities for chromatography resins in the world, and between 2017 and 2022 GE is annually investing up to USD 70 million in the production facility to significantly increase its capacity.
