Biotin-PEG-Mal, MW 7,500 is a PEG derivative with terminal biotin. Biotinylated polymer can strongly bind to proteins, such as avidin/streptavidin and is used for non-radioactive labeling as well as purification of proteins and other target molecules. The terminal maleimide is reactive with thiol containing molecule to generate a stable thioether bond. Reagent grade, for research purpose.
