SH-PEG4-COOH

SH-PEG4-COOH/Thiol-PEG4-COOH/COOH-PEG4-Thiol refers to a specific type of PEGylation reagent that has a reactive thiol (-SH) group at one end and a carboxylate group (-COOH) at the other end, connected by a flexible PEG4 (polyethylene glycol with a chain length of four) linker.PEGylation is a process in which polyethylene glycol (PEG) is covalently attached to a molecule, usually a protein or peptide, to improve its pharmacokinetic and therapeutic properties. The reactive thiol group of SH-PEG4-COOH can be used to react with a variety of functional groups, such as maleimide or iodoacetamide, to form stable covalent linkages between the PEGylating reagent and a target molecule.
