| abstract |
Aldehyde derivatives of polyethylene glycols and methods of making thereof are disclosed. These aldehyde derivatives can be used to make polyethylene glycol-hydrazines, polyethylene glycol-thiols, polyethylene glycol amines, and branched polyethylene glycols. PEG aldehyde derivatives or other functional PEG derivatives prepared from PEG aldehydes are useful for protein conjugation and surface modification. |
