Streptavidin and biotin binding
WebOct 31, 2024 · The binding of biotin to streptavidin is considered one of the strongest non-covalent bondings. This binding affinity is around 10 3 -10 6 times higher than the antigen … WebOur family of biotin-binding proteins includes streptavidin, avidin, and NeutrAvidin® protein. Each protein binds four biotins per molecule with high affinity and selectivity. Streptavidin is most commonly used — it is non-glycosylated and exhibits low levels of nonspecific binding
