What is Biotin Labeling?

Biotin, also known as vitamin B7, is a small biologically active molecule that acts as a co-enzyme in living cells. It can be coupled to oligonucleotides at the terminal and internal position at multiple sites. Biotin labeling (also called biotinylation) is the process of covalently attaching biotin to a protein, nucleic acid or other molecule, which has been widely used in numerous detection systems especially when the target of interest is expressed at low levels and cannot be detected by labeled antibodies alone. Generally, biotinylation is rapid, specific and is unlikely to perturb the natural function of the molecule due to the small size of biotin. Most importantly, many biotin molecules can be conjugated to an antibody with extremely high affinity, fast-on-rate, and high specificity, which does not appear in the conjugation with streptavidin and avidin. Through this amplification step, proteins which are expressed at low levels are more likely to be detected.
