Aeide-C1-NHS ester（Cat No.:I015837）is a compact heterobifunctional reagent designed for straightforward and efficient conjugation. It features an azide group, suitable for copper-catalyzed or strain-promoted click chemistry, paired with an NHS ester that reacts selectively with primary amines on proteins, peptides, or other biomolecules. With only a single carbon (C1) linker, this molecule offers minimal spacing between functional groups, enabling tight and precise linkages. Its simplicity makes it particularly useful in protein labeling, probe design, and drug delivery research where close proximity and stable covalent attachments are desired for functional outcomes.
