I. [Product Description]
NHS-PEG-Biotin is a multifunctional organic intermediate. Through the high-specific binding ability of the N-hydroxysuccinimide ester (NHS) active group and biotin, it enables the efficient coupling of biomolecules. Its core value lies in the excellent water solubility and steric hindrance adjustment function provided by the polyethylene glycol (PEG) segment. It can serve as a key reagent for catalyst-assisted protein modification and is widely used in the development of bioconjugation technology.
