NHS-dPEG®x-biotin
NHS-dPEG®x-biotin products are highly water-soluble, amine-reactive biotinylation reagents. Formulated with our single molecular weight, discrete PEG (dPEG®) linkers and spacers, these reagents are far superior to traditional hydrophobic biotinylation products such as LC biotin. NHS-dPEG®x-biotin products facilitate high degrees of biotin labeling for antibodies and other proteins, peptides, and other amine-containing biomolecules. The water-soluble, non-immunogenic dPEG® linker eliminates the concern for aggregation and precipitation that often accompanies the use of traditional hydrophobic products. NHS-dPEG®x-biotin products come in three lengths (4, 12, and 24 units) to enhance water solubility and maximize our customers’ ability to partner biotin-labeled molecules with avidin or streptavidin.
