Background: Streptavidin

Streptavidin is a 52.8 kDa protein from the bacterium Streptomyces avidinii. Streptavidin is a homo-tetramer forming a beta-barrel with an extraordinarily high affinity for biotin (also known as vitamin B7). It has a dissociation constant (Kd) on the order of ≈10−14 mol/L. https://en.wikipedia.org/wiki/Streptavidin#cite_note-1">The binding of biotin to streptavidin is one of the strongest non-covalent interactions known in nature and has a high resistance to organic solvents, denaturants, detergents, proteolytic enzymes, and extreme pH ranges or temperatures.
