Avidin

Avidin (/ˈævɪdɪn/) is a tetrameric biotin-binding protein produced in the oviducts of birds, reptiles and amphibians, and deposited in the whites of their eggs.

Etymology

The term "Avidin" is derived from the Latin word "avidus", which means "eager", reflecting the protein's high affinity for biotin.

Function

Avidin has a strong affinity to biotin, a type of vitamin, which is often used in various biological applications due to its binding properties. The binding of avidin to biotin is one of the strongest non-covalent interactions known in nature.

Structure

Avidin is a tetrameric protein, composed of four identical subunits, each of which can bind to biotin.

Applications

Due to its strong binding to biotin, avidin is often used in various biological and medical applications, such as affinity chromatography, immunohistochemistry, and western blotting.
