Description and Uses
Biotin-PEG4-acid is a biotinylation reagent which can react with amine molecules in the presence of activator EDC or HATU. PEG attached to the biotin gives an extended spacer arm that permits the biotin to reach into the binding pocket of the protein. The PEG moiety also increases solubility of Biotin-PEG conjugates considerably.
