Sigma Aldrich Fine Chemicals Biosciences ExtrAvidinR -Alkaline Phos
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(R) 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 has been conjugated to Alkaline Phosphatase and is used for various techniques.
