I. [Product Description] 
NHS-PEG-Lysines is a highly efficient organic intermediate. Through the efficient coupling reaction between the N-hydroxysuccinimide ester (NHS) active group and the amino group, it is widely used in the fields of biological coupling and material modification. Its core value lies in combining the excellent water solubility and biocompatibility of polyethylene glycol (PEG) with the multivalent reaction sites of lysine. It can be used as a catalyst or cross-linking agent to improve the reaction efficiency. This product is suitable for the functionalization modification of complex systems, with the advantages of both reaction activity and stability.
