3K-mPEG-SH-5g

3K-mPEG-SH (Methoxy Polyethylene Glycol Thiol, 3 kDa) is a functionalized polymer widely used for surface modification, protein PEGylation, and nanoparticle functionalization. The thiol (-SH) group allows for efficient conjugation to gold surfaces, maleimide-functionalized molecules, or other thiol-reactive substrates. The 3 kDa PEG provides steric stabilization and increases solubility and biocompatibility of biomolecules.
