I. [Product Description]
PBA-PEG-NHS (Pyridine-Polyethylene Glycol-N-Hydroxysuccinimide Ester) is a multifunctional organic intermediate that combines the highly reactive NHS ester group with the targeting properties of phenylboronic acid (PBA). It is widely used in the fields of bioconjugation and material modification. The PEG chain in its molecule can adjust the hydrophilic-hydrophobic balance, endowing the product with excellent water solubility and biocompatibility. It is suitable for protein labeling, nanocarrier construction, and polymer catalyst design.
