Biotinylation Reagents
Quanta BioDesign’s biotinylation reagents combine biotin with our single molecular weight, discrete PEG (dPEG®) linkers. Reactive groups on the dPEG® portions of these molecules permit many different types of conjugation reactions. Furthermore, our water-soluble dPEG® products will not cause aggregation and precipitation of conjugates. In contrast, standard LC-biotin reagents frequently cause these types of problems. Moreover, unlike traditional polymer PEG products, our dPEG® products have no dispersity (Ð = 1). Because our products contain a single chain length and molecular weight of PEG, unlike conventional PEG products, analyses of the resulting conjugates are greatly simplified.
