NHS-dPEG®4-biotin, product number 10200, is a constant favorite among our customers. It has been used or featured in numerous publications over the years since it was first introduced. Biotin is normally poorly soluble in water, but the amphiphilic dPEG® linker imparts excellent solubility in water or aqueous buffer and in organic solvent. The N-hydroxysuccinimidyl (NHS) moiety of NHS-dPEG®4-biotin reacts with free primary amines, such as the amines on the side chain of lysine, forming a stable amide bond. The biotin moiety is used in labeling experiments, supramolecular construction, affinity chromatography, the creation of biotinylated antibodies, and many other applications.
