M-PEG-NHS ester (MW 350)

M-PEG-NHS ester (MW 350) is utilized to modify active molecules, enhancing their antigenicity and immunogenicity, thus aiding in the preparation of injectable formulations. Modification of serine protease lumbrokinase (LK) with m-PEG-NHS ester does not affect its fibrinolytic and thrombolytic activities, indicating promising potential for application.
