설명

일반 설명

Pegylation of biotherapeutic drugs improves solubility, increases half life in the blood stream and reduces immunogenicity. Size exclusion chromatography (SEC) is often applied to characterize protein–polyethylene glycol (PEG) conjugates and establish the number of attached PEG chains, since SEC is a precise and robust technique that combines ease of set up and strainghtforward method develpopment.
This chromatogram shows the separation of four polyethyleneglycol polymers varying in molecular mass 8730 to 81,400 Da on two Zenix^® SEC-300 columns in series.
