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.
The 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.lthough the avidin-biotin system is simple to set up and use, it does have certain limitations. Because any biotinylated molecule will bind to any biotin-binding protein, these reagents must be used in combination with other detection-probe systems (i.e., primary-secondary antibodies) for multiplex experiments.
