Rabbit anti-avidin antibody can be used for indirect ELISA (1:100,000) and immunoelectrophoresis.

The presence of Scavidin in BT4C glioma cells was assessed by western blot using a rabbit anti-avidin antibody as the primary at a dilution of 1:4000. Lehtolainen, P.

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.
Rabbit anti-avidin antibody is immunospecific for egg white avidin by immunoelectrophoresis versus egg white avidin. No reactivity is observed versus streptavidin.
