M-PEG-NHS ester (MW 30000)

M-PEG-NHS ester (mPEG-SC) (MW 30000) is useful for modifying active molecules to enhance their antigenicity and immunogenicity, aiding in the formulation of injectable preparations. Modification of serine protease lumbrokinase (LK) with m-PEG-NHS ester does not affect its fibrinolytic and thrombolytic activities, indicating promising application potential.
