Descripción

Application

ExtrAvidin^® has been used to tetramerize aliquots to generate HLA-A2 tetramers.

Biochem/physiol Actions

Binding Activity: at least 10 μg biotin per mg

ExtrAvidin^® is prepared from egg white avidin. It is a tetrameric protein containing four high affinity binding sites for biotin. It combines the high specific activity of avidin with the low background staining of streptavidin, a biotin binding protein produced by the bacteria Streptomyces avidinii. It binds biotin with the high affinity of egg white avidin, however, it does not exhibit the unwanted non-specific binding reported for egg white avidin at physiological pH, such as the staining of mast cells.

Other Notes

A modified form of affinity purified egg white avidin.
