Avidin-Biotin Interaction | Thermo Fisher Scientific - US
WEBThe Avidin-biotin complex is the strongest known non-covalent interaction (K d = 10 -15 M) between a protein and ligand. The bond formation between biotin and Avidin is very rapid, and once formed, is unaffected by extremes of pH, temperature, organic solvents and other denaturing agents.
Avidin - Wikipedia
WEBBiotin - Avidin can bind up to four molecules of biotin simultaneously with a high degree of affinity and specificity. Avidin is a tetrameric biotin-binding protein produced in the oviducts of birds, reptiles and amphibians and deposited in the whites of their eggs. Dimeric members of the avidin family are also found in some bacteria. [1]

The Principles and Applications of Avidin-Based Nanoparticles in …
WEBJan 1, 2017 · Recently, chitosan nanoparticles modified with biotin and avidin were designed in which the mannose sugar and acetyl glucosamine of avidin were used to target the liver. Moreover, avidin allows the addition of multiple ligands on the surface to achieve highly specific targeting.
The avidin-biotin complex (ABC) method and other avidin-biotin binding ...
WEBThe binding of avidin to biotin is almost irreversible. By labeling a detection enzyme such as horseradish peroxidase with biotin, and a secondary antibody (reactive against the antigen detecting primary antibody) with biotin as well, these two compounds can then be linked irreversibly with avidin.
The hidden function of egg white antimicrobials: egg weight …
WEBApr 4, 2018 · Avidin is a key egg white antimicrobial protein with strong binding capacity for biotin, an essential growth and immune cell precursor. As such, it is assumed to have a pronounced, though still poorly explored, effect on hatchling phenotype.
WEBThe highly specific interaction of avidin with biotin (vitamin H) can be a useful tool in designing nonradioactive purification and detection systems. The extraordinary affinity of avidin for biotin (K a = 10 15 M-1) is the strongest known non-covalent interaction of a protein and ligand and allows biotin-containing molecules in a
Coupling of antibodies with biotin - PubMed
WEBThe avidin-biotin bond is the strongest known biological interaction between a ligand and a protein (Kd = 1.3 x 10-15 M at pH 5.0) (1). The affinity is so high that the avidin-biotin complex is extremely resistant to any type of denaturing agent (2).
