Diphenylthiol-Mal-PEG8-PEG4-Biotin is a biotinylation reagent with a diphenylthiol-maleimide group, which has been shown to have antibacterial properties. PEG attached to the biotin gives an extended spacer arm that permits the biotin to reach into the binding pocket of the protein or macromolecule. Reagent grade, for research use only.
