Characterization of Biomacromolecules by FPLC-MALS

The coupling of FPLC to MALS not only detects but also quantitatively determines the absolute molecular weight and size of each species, including the targeted molecules, impurities, and its aggregates.

Tosoh 2 Step mAb Purification Platform

Combining high performance protein A capturing and a single polishing step on a salt-tolerant anion exchange resin, downstream costs were reduced by 45% in this Tosoh 2-step process for mAb purification.
