  • Southwestern blotting
  • Western blotting
  • Immunocytochemistry

Biochem/physiol Actions

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.

Physical form

Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 0.05% MIT

Preparation Note

Affinity purified protein

Storage and Stability

Store at 2-8 °C. Do Not Freeze. If slight turbidity occurs upon prolonged storage, clarify the solution by centrifugation before use.
