Protein glycaNon is a non-enzymaNc reacNon of proteins with simple reducing sugars such as glucose and fructose . The glycaNon reacNon rate is typically low for mAbs and fusion proteins and due to the many potenNal glycaNon reacNon sites and instrumental sensiNvity limits, the idenNficaNon and characterisaNon of glycaNon in biotherapeuNcs can be challenging. GlycaNon is idenNfied via +162.05
