I. [Product Description]
Biotin-PEG-SG (Biotin-Polyethylene Glycol-Succinimidyl Glutarate) is a high-performance organic intermediate that combines the high-affinity properties of biotin with the steric hindrance effect of the PEG chain. This compound enables efficient coupling reactions through its active ester group and can serve as a key catalyst for biomolecule modification. It is widely used in the construction of bioconjugation systems, and its modular design significantly enhances the reaction selectivity and product purity.
