Concentration	1.0 mg/mL - lot specific
Conjugation	Biotin
Storage Condition	Store vial at 4° C prior to restoration.   For extended storage aliquot contents and freeze at -20° C or below.  Avoid cycles of freezing and thawing.  Centrifuge product if not completely clear after standing at room temperature.  This product is stable for several weeks at 4° C as an undiluted liquid.  Dilute only prior to immediate use.
Database Link	UniProt ID P02701
Background	Avidin is a glycoprotein with a molecular weight of approximately 62.4 kDa. Avidin is a biotin binding protein that shows high sequence homology in birds, reptiles and amphibians. Hen egg white avidin is a tetrameric protein composed of four identical subunits, each with the ability to bind biotin with high affinity and specificity (Kd ~ 1015 M). In biotechnology, the functional consequence of tetrameric biotin binding is signal amplification. Biotin-avidin bridging is a great way to increase signal strength while maintaining specificity. The sequence of avidin only shows 30% homology with streptavidin, and anti-avidin and anti-streptavidin antibodies are not immunologically cross reactive. Biotin is widely used throughout the biotechnology industry to conjugate proteins for biochemical assays. Biotin's small size typically does not affect the biological activity of protein upon biotinylation. Biotinylated proteins of interest can be enriched from a sample due to highly stable interactions.
Synonyms	rabbit anti-Avidin Antibody biotin Conjugation, Biotin conjugated rabbit anti-Avidin antibody, Avidin BAC, Anti-Avidin biotin Antibody, Egg White
Note	Anti-Avidin Antibody Biotin Conjugated has been tested by ELISA and western blot and is suitable for immunohistochemistry, immunomicroscopy as well as other antibody based assays using streptavidin or avidin conjugates requiring lot-to-lot consistency.
