Product number 10198, NHS-dPEG®12-biotin, is a longer version of the constantly popular product number 10200, NHS-dPEG®4-biotin. This product has been used and featured in numerous publications 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®12-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, pull-down assays, the creation of biotinylated antibodies, and many other applications.
