Application
Avidin egg white was used in an assay using functionalized xenon as a biosensor to detect biotin-avidin binding. Egg white was used at 80 nmol.
Egg white avidin has been used as a cross-linker for biotin-conjugated antibodies. The product has also been used as a blocking agent in ELISA applications.

General description
Avidin protein is a 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.
Other Notes
One unit will bind 1.0 μg of d-biotin.

Arrays of individual molecules can combine the advantages of microarrays and single-molecule studies. They miniaturize assays to reduce sample and reagent consumption and increase throughput, and additionally uncover static and dynamic heterogeneity usually masked in molecular ensembles. However, realizing single-DNA

Advanced stage cancer treatments are often invasive and painful-typically comprised of surgery, chemotherapy, and/or radiation treatment. Low transport efficiency during systemic chemotherapy may require high chemotherapeutic doses to effectively target cancerous tissue, resulting in systemic toxicity. Nanotherapeutic platforms have been

The biofunctionalization of nanopatterned surfaces with DNA origami nanostructures is an important topic in nanobiotechnology. An unexplored challenge is, however, to co-immobilize proteins with DNA origami at pre-determined substrate sites in high contrast relative to the nontarget areas. The immobilization
