Application
ExtrAvidin® has been used to tetramerize aliquots to generate HLA-A2 tetramers.
Biochem/physiol Actions
Binding Activity: at least 10 μg biotin per mg
ExtrAvidin® is prepared from egg white avidin. It is a tetrameric protein containing four high affinity binding sites for biotin. It combines the high specific activity of avidin with the low background staining of streptavidin, a biotin binding protein produced by the bacteria Streptomyces avidinii. It binds biotin with the high affinity of egg white avidin, however, it does not exhibit the unwanted non-specific binding reported for egg white avidin at physiological pH, such as the staining of mast cells.

The tumor suppressor p53 is widely dysregulated in cancer and represents an attractive target for immunotherapy. Because of its intracellular localization, p53 is inaccessible to classical therapeutic monoclonal antibodies, an increasingly successful class of anticancer drugs. However, peptides derived from

Surface plasmon polaritons (SPPs) are responsible for exotic optical phenomena, including negative refraction, surface enhanced Raman scattering, and nanoscale focusing of light. Although many materials support SPPs, the choice of metal for most applications has been based on traditional plasmonic

The ability to detect a protein is always limited to the sensitivity of the assays available. Progress in improving the sensitivity of protein detection will allow a more complete understanding of biological systems. Of particular interest to the field of

A growing number of biophysical techniques use immobilized reactants for the quantitative study of macromolecular reactions. Examples of such approaches include surface plasmon resonance, atomic force microscopy, total reflection fluorescence microscopy, and others. Some of these methods have already been
