  2. Biotinylated Proteins

Biotinylation is the process of covalently attaching biotin to a molecule, such as amino acid or protein. Generally, Biotinylation is rapid, specific and is unlikely to disturb the natural function of the molecule owing to the small size of biotin. Biotinylation is widely used in biomedical sciences since biotin binds to streptavidin/avidin with an extremely high affinity, fast on-rate, and high specificity. Significantly, biotinylated proteins are widely used as a molecular tool in biotechnological applications. Avi-tag is a small synthetic 15-amino-acid peptide which is effectively biotinylated by BirA, the E. coli biotin ligase, in vitro or in vivo. Avi-Tag can be translationally fused at the N or C terminus of proteins to produce biotin-tagged proteins for isolating protein or labeling for microscopy.
