General description

Avidin is homotetrameric protein (68kDa) obtained from egg whites and binds strongly to biotin. Thus, avidin-biotin association has been utilized in immunoassays to detect the localization of antigens in tissues. The use of avidin-biotin immunoassay enhances the sensitivity of the technique and facilitates the detection of antigens in low quantities.

Application

Avidin-Peroxidase has been used for ELISA applications. The product can also be used for western blot applications at dilutions ranging from 1:400,000 to 1:800,000.
Western blot analysis of proteins in HUVEC cells that had underwent cell surface biotinylation were detected using HRP-conjugated avidin at 33.3 ng/ml.

Physical form

Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 0.05% MIT.

Preparation Note

Affinity purified protein.

CD4(+)CD25(+high) T cells are potent regulators of autoreactive T cells. However, it is unclear how regulatory CD4(+)CD25(+high) cells discriminate between desirable inflammatory immune responses to microbial Ags and potentially pathologic responses by autoreactive T cells. In this study, an in
