特点和优势

Biotin-dPEG®4-TFP ester has 2,3,5,6-tetrafluorophenyl (TFP) moiety which hydrolyzes more slowly than NHS ester in aqueous media and are more reactive towards amines than NHS esters. The single molecular weight Biotin-dPEG®4-TFP ester has a long spacer of precise length (19.2 Å) between the biotin moiety and the labeled molecule. This dPEG spacer imparts a high degree of water solubility to the biotin label. 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.
