Acciones bioquímicas o fisiológicas
Avidin is a tetrameric or dimeric biotin-binding protein produced in the oviducts of birds, reptiles and amphibians and deposited in the whites of their eggs. It consists of four high affinity binding sites for biotin. ExtrAvidin® is prepared from egg white avidin. It is a modified form of affinity purified avidin with high specific activity of avidin and low background staining of streptavidin. It is a biotin binding protein produced by the bacteria Streptomyces avidinii. ExtrAvidin-Peroxidase may be used in conjunction with biotin in different techniques.
