Native Chicken Egg White Avidin

Cat.No.: Avidin-155C
Product Overview: Purified Native Chicken Egg White Avidin. CAS Number: 1405-69-2; E.C. Number: 215-783-6
Description: Avidin is a tetrameric protein. In chicken egg white, avidin makes up approximately 0.05% of total protein (approximately 1.8 mg per egg). The tetrameric protein contains four identical subunits (homotetramer) each of which can bind to biotin (Vitamin B7, vitamin H) with a high degree of affinity and specificity.Avidin"s affinity for biotin is exploited in wide ranging biochemical assays, including Western Blot, ELISA, ELISPOT and pull-down assays. Avidin immobilized onto solid supports is also used as purification media to capture biotin-labelled protein or nucleic acid molecules. For example, cell surface proteins can be specifically labelled with membrane impermeable biotin reagent, then specifically captured using an avidin-based support.
