I. [Product Description]
NHS-PEG-His (N-hydroxysuccinimide ester-polyethylene glycol-histidine) is a highly active organic intermediate, possessing both efficient catalytic performance and biocompatibility. The NHS ester group in its core structure can specifically bind to amino groups, making it suitable for the directional modification of proteins or polypeptides. The PEG chain provides excellent water solubility and spatial stability, and it is a key intermediate in bioconjugation reactions and the synthesis of functional materials.
