Description

General description

Avidin is homotetrameric protein (68kDa) that is obtained from egg whites. This egg protein binds strongly to biotin. Thus, avidin-biotin association has been utilized in immunoassays to detect the localization of antigens in tissues[1]. The use of avidin-biotin immunoassay enhances the sensitivity of the technique and facilitates the detection of antigens in low quantities.

Application

Avidin-FITC from egg white has been used for immunohistochemistry applications[2].

To determine the amount of labeled polyclonal IgG present in spores in an IgG prep. A known concentration of FITC avidin from egg white and biotin-IgG avidin was used in excess at 300nm.[3]
