description Product Description
Used extensively in bioconjugation processes, it serves as a linker to attach polyethylene glycol (PEG) chains to proteins, peptides, or other biomolecules. This modification enhances solubility, stability, and reduces immunogenicity, making it valuable in drug delivery systems and therapeutic protein development. It is also employed in surface modification of nanoparticles to improve their biocompatibility and circulation time in vivo. Additionally, it plays a role in creating PEGylated hydrogels for controlled drug release and tissue engineering applications.
