Scientific Data Images for Streptavidin Antibody

Detection of Streptavidin antibody by Western Blot.

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 (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.
