I. [Product Description]
SH-PEG-NHS (Thiol-Polyethylene Glycol-N-Hydroxysuccinimide Ester) is a bifunctional crosslinking agent, possessing both the specific reactivity of thiol (-SH) and the high-efficiency coupling ability of NHS ester. As an organic intermediate/ pharmaceutical intermediate, its PEGylation modification can significantly improve the solubility and stability of biomolecules, and it has important application value in the fields of nanomaterial preparation, biosensor development, and polymer material modification.
