Avidin is a glycoprotein that is primarily found in egg whites, particularly in the egg white of chicken eggs. It is known for its strong affinity for biotin, a vitamin that plays a crucial role in various metabolic processes. Avidin is composed of four identical subunits, each capable of binding one molecule of biotin, resulting in a tetrameric structure. This binding is non-covalent and extremely stable, making avidin a valuable tool in biochemistry and molecular biology, particularly in applications such as affinity chromatography and biotinylation assays. Avidin is also characterized by its high molecular weight and is often used in research and diagnostic applications due to its ability to form complexes with biotinylated molecules. Additionally, avidin is heat-stable and retains its binding properties even after exposure to elevated temperatures. However, it is important to note that avidin can induce an immune response in some individuals, and its use in therapeutic applications requires careful consideration of potential allergic reactions.
