Avidin is a biotin-binding protein that is believed to function as an antibiotic in the eggs of birds, reptiles and amphibians. Chicken avidin has a mass of 67,000-68,000 Daltons and is formed from four 128 amino acid-subunits, each binding one molecule of biotin.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.
