Biotinylation Guidelines—Creating Biotinylated DNA

WebbThese different formats can be used for protein purification and enrichment, where a biotinylated antibody (or other biotinylated molecule) is attached to the Streptavidin and … In biochemistry, biotinylation is the process of covalently attaching biotin to a protein, nucleic acid or other molecule. Biotinylation is rapid, specific and is unlikely to disturb the natural function of the molecule due to the small size of biotin (MW = 244.31 g/mol). Biotin binds to streptavidin and avidin with an extremely high affinity, fast on-rate, and high specificity, and these interactions are exploited in many areas of biotechnology to isolate biotinylated molecules of interest. Biotin-bin… WebbThe magnetic beads for separation of biotinylated biomolecules have a Streptavidin ligand. Streptavidin is an M r 60 000 protein from Streptomyces avidinii, and is a tetramer containing four biotin binding sites.
