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 and binds biotin with high specific activity of avidin with the low background staining of streptavidin, a biotin binding protein produced by the bacteria Streptomyces avidinii. ExtrAvidin® is covalently conjugated to Cy3 dye and is used for various techniques.

Physical form

Solution in 0.01 M phosphate buffered saline, containing 1% bovine serum albumin and 15 mM sodium azide

Preparation Note

Affinity purified protein

Purpose. To measure the chemotherapeutic effects of focal melphalan (intravitreal and subconjunctival) on tumor burden, hypoxia, and vasculature in LHBETATAG murine retinoblastoma model. Methods. LHBETATAG transgenic mice were treated with a single 1 mcg intravitreal injection of melphalan, 100 mcg subconjunctival
