설명

애플리케이션

Biotin-dPEG^®₄-TFP ester is an amphiphilic and hydrolytically stable compound used as a cross-linking reagent in biotinylations reactions.

특징 및 장점

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.
