Description:
Agrowingnumberofantibodiesandantibodyfusionsarecurrentlyusedastherapeuticagents.AconservedN-glycanatAsn297oftheFcregionofIgGiscriticalforfunctionalactivity.Moreover,someantibodieshaveadditionalN-glycansthat,togetherwiththeconservedsite,affectrecognition,half-life,andimmunereactions.Antibodyglycosylationisheterogeneous,andvariablesincellculturecanincreaseglycandiversity.Monitoringglycosylationduringproductionisessentialtoobtainthecorrectglycoproteinforms.
