Amine Reactive Biotinylation Reagents
Quanta BioDesign’s amine-reactive dPEG® biotinylation reagents are high-purity, highly water-soluble products. These single molecular weight, discrete chain length PEG (dPEG®) products include our wildly popular NHS esters, our hydrolysis-resistant TFP esters, biotin-dPEG®-acids, and our unique cleavable biotin product. All of our biotinylation products facilitate high degrees of biotin labeling for antibodies and other proteins, peptides, and other amine-containing biomolecules. Moreover, the water-soluble, non-immunogenic dPEG® linker eliminates aggregation and precipitation concerns that often accompany the use of traditional hydrophobic products such as LC biotin. Furthermore, our products come in multiple lengths to enhance water solubility and maximize our customers’ ability to partner biotin-labeled molecules with avidin or streptavidin.
