Modification of Glycans in Bioprocessing with Ryan Boniface Protein quality determines clinical behavior. Glycosylation is a key product quality attribute for many biotherapeutic proteins expressed by mammalian cells. N-linked glycans can display macro- and microheterogeneity with a degree of variation that depends on several factors. It’s often challenging to predict, achieve, and maintain preferred glycosylation profiles. For an “Ask the Expert” webinar on 15 June 2016, bioproduction scientist Ryan Boniface of Thermo Fisher Scientific explored approaches to modifying glycan patterns.…
