Egg whites contain high levels of avidin, a protein that binds biotin strongly. When cooked, avidin is partially denatured and binding to biotin is reduced. HABA dye is bound to avidin or streptavidin and yields a characteristic absorbance. As a basically charged glycoprotein, avidin exhibits non-specific binding in some applications. Deglycosylated avidin (NeutrAvidin) is more comparable to the size, pI, and nonspecific binding of streptavidin. Avidin biotin media is used in the purification process of biotin/avidin and their derivatives. She acted in a negative role in the drama "Oba Ayemath Avidin". Dimeric members of the avidin family are also found in some bacteria. Avidin is the other most notable biotin-binding protein. Avidin is an antinutrient found in active form in raw egg whites.
