Properties

Description

Azido-PEG7-NHS ester is a widely used PEG reagent that features an azide group along with a terminal NHS ester. The hydrophilic nature of the PEG spacer enhances its solubility in water-based environments. The azide can engage in reactions with alkynes, BCN, and DBCO through click chemistry to form stable triazole linkages. Additionally, the NHS ester is suitable for labeling primary amines t-found in proteins, amine-modified oligonucleotides, and other amino-containing compounds.
