Features and Benefits
Biotin-dPEG®12-TFP ester has 2,3,5,6-tetrafluorophenyl (TFP) moiety whcih hydrolyze more slowly than NHS esters in aqueous media and is more reactive towards amines than NHS esters. The single molecular weight Biotin-dPEG®12-TFP ester has a long spacer of precise length (47.6 Å) between the biotin moiety and the labeled molecule. This dPEG spacer imparts a high degree of water solubility to the biotin label. For biotinylated peptides and proteins, the PEG spacer dramatically reduces aggregation and precipitation of the modified molecule and reduces non-specific binding of the molecule, both of which are common problems with molecules that have been biotinylated with the widely used NHS-LC-biotin.
