Description

Biotin-PEG3-Bromide is a short PEG linker featuring a biotin group and a bromide. The bromide group serves as a leaving group that can undergo substitution reactions with nucleophiles, such as primary amines (-NH2) or thiols (-SH), enabling the attachment of the biotin-PEG3 moiety to biomolecules or surfaces. Biotin-PEG3-bromide can be used to label proteins or antibodies with biotin for subsequent detection, purification, or immobilization using avidin-based systems. This is particularly useful in techniques such as Western blotting, immunohistochemistry, or enzyme-linked immunosorbent assays (ELISA).
