Biotin-PEG3-Maleimide enables simple and efficient biotinylation of antibodies, cysteine-containing peptides and other thiol-containing molecules. The maleimide group reacts specifically and efficiently with reduced thiols (sulfhydryl groups, –SH) at pH 6.5 to 7.5 to form stable thioether bonds. The hydrophilic polyethylene glycol (PEG) spacer arm imparts water solubility that is transferred to the labelled molecule, thus reducing aggregation of labelled proteins stored in solution.
Colourless to slightly yellow amorphous solid
