NHS-dPEG®24-biotin, product number QBD-10774, is an amine-reactive biotinylation product containing a single molecular weight, discrete PEG (dPEG®) linker that is 76 atoms long. Although biotin usually is poorly soluble in water, the amphiphilic dPEG® linker creates excellent water solubility while maintaining organic solvent solubility. The N-hydroxysuccinimidyl (NHS) moiety of NHS-dPEG®24-biotin reacts optimally with free primary amines in the pH range 7.0 – 7.5., forming stable amide bonds. Unlike the classic, hydrophobic biotin linkers, LC-biotin and LC-LC-biotin, NHS-PEG®24-biotin does not cause protein aggregation due to over-labeling of the target molecule. Labeling experiments, supramolecular construction, affinity chromatography, pull-down assays, the creation of biotinylated antibodies, and many other applications can use NHS-dPEG®24-biotin to take advantage of the exceptionally high affinity between biotin and avidin or streptavidin.
