WebIn the claudin-1 −/− mouse epidermis (d–f), the diffusion of injected biotin tracer is not prevented by the occludin-positive TJs ( arrows ). Instead, the biotin tracer passes through these TJs to reach the border between stratum granulosum and stratum corneum. Bar: 10 μm. SC, stratum corneum. 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.
