m-PEG-NHS ester (MW 550)

m-PEG-NHS ester (MW 550) can be used to modify active molecules and improve their antigenicity, immunogenicity, and help prepare injection preparations. The modification of serine protease lumbrokinase (LK) by m-PEG-NHS ester does not affect its strong fibrinolytic and thrombolytic activities, and has good application prospects.
