[Product Description]
BSA-PEG-NHS is a multifunctional organic intermediate that enables efficient coupling reactions through the N-hydroxysuccinimide ester (NHS) activating group. It is widely used in the field of biomolecule modification. Its core value lies in combining the stability of bovine serum albumin (BSA) and the biocompatibility of polyethylene glycol (PEG). It can be used as a pharmaceutical intermediate or catalyst, significantly enhancing the water solubility and reactivity of the complex.
