    Alkyne-PEG4-NHS Ester is a labeling reagent that can be used to modify primary amine groups (e.g., a side chain of lysine residues or aminosilane-coated surfaces) with a terminal alkyne group via a stable, covalent amide bond. The terminal alkyne group can be reacted with azides via CuAAC enabling efficient and specific conjugation of derivatized molecules in biological samples.
