General description
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 has been conjugated to Alkaline Phosphatase and is used for various techniques.
Application
ExtrAvidin™ -Alkaline Phosphatase has been used in:
- Dot blot
- Immunohistochemistry (formalin-fixed, paraffin-embedded sections)
- Indirect ELISA
- Enzyme linked immunosorbent assay (ELISA)
- Enzyme-linked immunosorbent spot (ELISPOT) analysis
- Competitive ELISA
Biochem/physiol Actions
Alkaline Phosphatase catalyzes the hydrolysis of esters to yield phosphoric acid. It is also facilitate the transport of substances across membranes.
