Biotin-PEG3-NHS ester (CAT: I014201) is a bioconjugation reagent widely used in various applications involving the modification of biomolecules. This compound contains a biotin group, a polyethylene glycol (PEG) spacer of three units, and an N-hydroxysuccinimide (NHS) ester functionality. The NHS ester moiety enables efficient and stable coupling of the reagent to primary amines on target molecules, such as proteins and peptides. Biotin-PEG3-NHS ester serves as a valuable tool in the development of bioconjugates, affinity-based assays, and studies involving the immobilization, labeling, or purification of biomolecules.
