Detection of Streptavidin by Western Blot. Western blot shows recombinant Streptavidin. PVDF membrane was probed with 0.5 µg/mL of Rabbit Anti-Streptavidin Monoclonal Antibody (Catalog # MAB9020) followed by HRP-conjugated Anti-Rabbit IgG Secondary Antibody (Catalog # HAF008). A specific band was detected for Streptavidin at approximately 13 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

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 (K_d) on the order of ≈10⁻¹⁴ mol/L. 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.
