The dPEG®-Biotin Advantage
Biotinylation is one of the most widely used bioconjugation techniques. It can add a biotin tag to antibodies, proteins, and other molecules for high-affinity binding with streptavidin reagents. Our dPEG® spacers create a significant advantage over aliphatic biotin compounds, such as the popular NHS-LC-biotin reagent. The SuperHydrophilic™ dPEG® spacers prevent antibody or protein denaturation, aggregation, or precipitation, which is often a problem when using hydrophobic biotinylation compounds. Discover the dPEG® difference with our water-soluble biotinylation reagents and our wide selection of conjugation chemistries.
