Avidin is a protein found in the eggs of birds, amphibians, and reptiles. It is produced in the oviducts of these animals.hen an egg is cooked, the avidin inside the egg white is deactivated, but biotin present in the egg yolk is unaffected. Ad. A biotin deficiency causes hair loss, a scaly rash around the eyes, and high cholesterol in the blood.
Avidin-biotin binding is the strongest known non-covalent interaction between a protein and ligand. The bond formation between biotin and avidin is very rapid, and once formed, is unaffected by extremes in pH, temperature, organic solvents and other denaturing agents.n contrast to avidin, though, streptavidin is not glycosylated, which makes the protein less-prone to nonspecific binding in IHC applications. Pierce products use a recombinant form of streptavidin, having a mass of 53kDa and a near-neutral pI.
