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. 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.
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.

Thalamic neuronal degeneration after neocortical lesions involve both anterograde and retrograde components. This study deals with the thalamic microglial response after neocortical aspiration lesions, using fluorogold fluorescent prelabeling, to identify retrogradely degenerating thalamocortical neurons, combined with histochemical or immunohistochemical staining
