Description

Biotin-PEG3-Mal can be used to label proteins or peptides containing exposed cysteine residues. The maleimide group reacts specifically with thiol (-SH) groups, forming stable thioether bonds. This allows for site-specific labeling of proteins with biotin, which can then be detected using streptavidin-based assays, such as Western blotting, ELISA, or immunohistochemistry.
