Azido-PEG10-NHS ester（Cat No.:I045913）is a heterobifunctional linker designed for precise and efficient bioconjugation. It carries an azide group for click chemistry reactions—either copper-catalyzed or strain-promoted—and an NHS ester that reacts selectively with primary amines on proteins, peptides, or other biomolecules. The PEG10 spacer offers enhanced solubility, reduced steric hindrance, and moderate chain length, ensuring flexibility while maintaining functional stability in aqueous and biological systems. This reagent is particularly useful for protein labeling, drug delivery, nanomaterial functionalization, and diagnostic probe development where controlled spacing and stable conjugates are essential.
