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.
The antibody binds to the avidin molecule without interfering with the biotin-binding reaction. The product reacts specifically with egg white avidin, ExtrAvidin and their complexes formed with biotin. The antibody shows no cross-reaction with streptavidin.
Immunogen
Purified egg white avidin.
Application
Immunohistochemistry was performed on 4% paraformaldhyde fixed mouse brain sections. After incubation with primary antibody, the sections were treated with a biotinylated secondary antibody and the with texas-red conjugated egg white avidin. The signal was then amplified by treating samples with mouse monoclonal anti-avidin (A5680) at a dilution of 1:1000.
Mouse Monoclonal Anti-Avidin antibody has been used for ELISA assays at 3-5mg/ml. The antibody has also been used for immunocytochemistry at 1:2000 or 1:4000 dilutions.
Physical form
The product is provided as ascites fluid with 0.1% sodium azide as a preservative.

As elevated levels of glycated IgG have been detected in the plasma of patients with diabetes mellitus, a disease associated with increased susceptibility to infection, we have investigated whether glycation of MoAbs affects the kinetics and/or affinity of antigen binding.

Immunodetection techniques are dependent on enzyme-protein conjugates for the visualization of antigen-antibody complexes. One of the most widely used is the avidin-biotin-peroxidase complex (ABC) method. However, treatment of certain tissues with ABC reagents alone may result in high background, which

The A-class of the erythropoietin-producing hepatocellular carcinoma cell-derived (EphA) tyrosine kinase receptors and their ligands, the A-ephrins, play critical roles in the specification of topographic axon projection maps during development. In this study, the role of the EphA subfamily in
In mammals, the nucleolus is thought to be a stress sensor; upon cellular stress conditions, a release of nucleolar proteins and down-regulation of rDNA transcription occurs. Since yeast Rrn3p is a homolog of the mammalian RNA polymerase I (Pol I)-specific
