I. [Product Description]
NHS-PEG-NTA, N-hydroxysuccinimide ester-polyethylene glycol-nitrilotriacetic acid ester, is a multifunctional organic intermediate with both high-efficiency coupling ability and metal chelating properties. Its PEG segment can significantly improve water solubility and biocompatibility. It is widely used in protein modification, nanomaterial synthesis, and biocatalysis fields, and is the core material for the development of pharmaceutical intermediates and the assembly of complex molecules.
