WebMar 25, 2024 · Researchers have been using the interaction between streptavidin and biotin for the last 25 years to study, for instance, the folding and unfolding of proteins. The streptavidin is then attached to the tip of an atomic force microscope, working as a handle to pull on the protein through the streptavidin/biotin interaction.

Although SA’s four subunits have the same affinity, we find that the forces required to break the SA/biotin bond depend strongly on the attachment geometry. With AFM-based single-molecule force spectroscopy (SMFS), we measured unbinding …
WebThe streptavidin-biotin system is a protein-ligand interaction present in nature that has been successfully used in a number of applications including detection of proteins, … Streptavidin /ˌstrɛpˈtævɪdɪn/ is a 52 kDa protein (tetramer) purified from the bacterium Streptomyces avidinii. Streptavidin homo-tetramers have an extraordinarily high affinity for biotin (also known as vitamin B7 or vitamin H). With a dissociation constant (Kd) on the order of ≈10 mol/L, the binding of biotin to streptavidin is one of the strongest non-covalent interactions known in natur…
WebBoth biotin and the streptavidin remain active after dissociation and both molecules can therefore be re-used. The efficiency of the regeneration allowed solid supports with streptavidin to be used many times, here exemplified with the multiple re-use of streptavidin beads used for sample preparation prior to automated DNA sequencing.
