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] In chicken egg white, avidin makes up approximately 0.05% of total protein (approximately 1800 μg per egg).
