Biotin-PEG-NHS is a heterobifunctional PEG derivative with a biotin group and an N-hydroxysuccinimide (NHS) ester group. The NHS ester group of Biotin-PEG-NHS reacts specifically with primary amines to form stable amide bonds, enabling the conjugation of biotin to proteins, peptides, nucleic acids, or other molecules with primary amine groups. Biotin, also known as vitamin B7 or vitamin H, is widely used as a molecular tag due to its strong and specific binding affinity to avidin and streptavidin proteins. This enables the labeled molecules to be easily detected, purified, or immobilized using avidin or streptavidin-based detection systems. Biotin-PEG-NHS finds applications in various fields, including protein labeling, immunoassays, cell surface labeling, and affinity purification.
