Product is a thiolated carboxylic-polyethylene . 4a;-sulfanyl-? carboxy PEG (HS-PEG-COOH) heterobifunctional PEGs with functional end-groups of very different reactivity. HS-PEG-COOH inhibits nonspecific binding to living cells.
Synonyms: HS-PEG-COOH; Thiol-PEG-Carboxyl, HS-PEG-COOH
Linear Structural Formula: HS(CH2CH2O)nCH2COOH
Application: HS-PEG-COOH may be tethered to the gold nanoparticle end during the fabrication of epidermal growth factor (EGF)-conjugated surface-enhanced Raman spectroscopy (SERS) nanoparticles. HS-PEG-COOH was coated onto silicon-on-insulator photonic biosensor chips. Quantum dots (QD)/ virus-like particles (VLPs) could be obtained only from HS-PEG-COOH-coated QDs. It may be used to stabilize nanoparticles and prevent its aggregation.
