Streptavidin Antibody

Product Data

• Application: ELISA, IHC, WB
• Recommended Dilution: WB: 1:3,000 - 1:12,000; IHC: 1:1,500 - 1:5,000; ELISA: 1:200,000
• Reactivity: Streptomyces avidinii
• Antibody Host: Rabbit
• Clonality: Polyclonal
• Immunogen: Streptavidin [Streptomyces avidinii]
• Specificity: Anti-Streptavidin antibody is an IgG fraction antibody purified from monospecific antiserum by a multi-step process which includes delipidation, salt fractionation and ion exchange chromatography followed by extensive dialysis against the buffer stated above. Assay by immunoelectrophoresis resulted in a single precipitin arc against anti-Rabbit Serum as well as purified and partially purified Streptavidin [Streptomyces avidinii]. No cross reactivity occurs against Avidin.
• Buffer: 0.02 M Potassium Phosphate, 0.15 M Sodium Chloride, pH 7.2
• Concentration: 1.0 mg/mL - lot specific
• Conjugation: Unconjugated
• Storage: Store vial at -20° C or below prior to opening. This vial contains a relatively low volume of reagent (25 µL). To minimize loss of volume dilute 1:10 by adding 225 µL of the buffer stated above directly to the vial. Recap, mix thoroughly and briefly centrifuge to collect the volume at the bottom of the vial. Use this intermediate dilution when calculating final dilutions as recommended below. Store the vial at -20°C or below after dilution. Avoid cycles of freezing and thawing.
• Stability: Expiration date is three (3) months from date of receipt.
• Shipping: Ambient
• Background: Streptavidin antibody is a 60 kDa protein purified from the bacterium Streptomyces avidinii. Streptavidin homo-tetramers have an extraordinarily high affinity for biotin (also known as vitamin B7). With a dissociation constant (Kd) on the order of ≈10−14 mol/L,[1] the binding of biotin to streptavidin is one of the strongest non-covalent interactions known in nature. Streptavidin is used extensively in molecular biology and bio-nanotechnology due to the streptavidin-biotin complex's resistance to organic solvents, denaturants (e.g. guanidinium chloride), detergents (e.g. SDS, Triton), proteolytic enzymes, and extremes of temperature and pH. Anti-STREPTAVIDIN antibody is ideal for investigators involved in GFP and Epitope research.
• Synonyms: rabbit anti-Streptavidin Antibody, rabbit anti Streptavidin
• Note: Anti-Streptavidin antibody has been tested by ELISA and dot blot and is suitable for western blot, and immunohistochemistry, as well as other assays requiring lot-to-lot consistency.
