Description

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.
