Biotin-PEG4-S-S-PEG8-DBCO functions as a cleavable reagent for biotinylating proteins or cell surfaces with primary amines. Its disulfide bond enables biotin removal using reducing agents like DTT, BME, or TCEP, ensuring reversible labeling for dynamic studies. The DBCO can partake in click reactions with azides. The PEG chains improve the water solubility of the molecule. Reagent grade, for research use only.
