说明

特點和優勢

Biotin-dPEG^®₂₃-MAL takes advantage of the well-known, specific Michael reaction between a maleimide group and a free sulfhydryl to allow site-specific biotin labeling of molecules in aqueous media within the pH range of 6.5 – 7.5. The single molecular weight dPEG^® spacer (94.1 Å) provide precise spacing between the biotin moiety and the labeled molecule. The dPEG^® spacer imparts water solubility to the labeled molecule while reducing immunogenicity, aggregation, and precipitation of labeled biomolecules or other labeled compounds.
