Biotin-PEG-NHS ester

Biotin-PEGn-NHS Ester is primarily used for efficiently biotinylating amines in proteins, antibodies, and other biomolecules to facilitate detection or purification via streptavidin-biotin interaction. Its key benefits include the water-soluble PEG spacer which reduces steric hindrance and increases reactivity, while the NHS ester group ensures stable amide bond formation.
