N-Glycan Analysis of Biotherapeutic Proteins
In addition, some IgGs such as Erbitux (cetuximab) are also N-glycosylated within the fragment antigen-binding (Fab) region. Figure 1A represents some of the therapeutic effects of biantennary N-glyca…

Implications of Cell Culture Conditions on Protein Glycosylation
Multi-chain proteins, such as IgG antibodies, additionally have a quaternary structure resulting from structural associations between the subunits.
The choice of host-cell line for recombinant pro…
