I. [Product Description]
NHS-PEG-SPDP (N-Hydroxysuccinimide Ester-Polyethylene Glycol-3-(2-Pyridyldithio)propionic Acid N-Hydroxysuccinimide Ester) is a bifunctional crosslinking agent with both efficient coupling and controllable cleavage properties. It is widely used as an organic intermediate and a catalyst for bioconjugation reactions. The PEG segment in its structure significantly enhances water solubility and biocompatibility. The SPDP group can achieve targeted release through thiol-disulfide exchange, making it an ideal choice for constructing dynamic linkage systems.
