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.

Stable insertion of the retroviral DNA genome into host chromatin requires the functional association between the intasome (integrase·viral DNA complex) and the nucleosome. The data from the literature suggest that direct protein-protein contacts between integrase and histones may be involved

Tregs are important mediators of immune tolerance to self antigens, and it has been suggested that Treg inactivation may cause autoimmune disease. Therefore, immunotherapy approaches that aim to restore or expand autoantigen-specific Treg activity might be beneficial for the treatment
