• Catalog Number: orb1463566
• Category: Antibodies
• Description: Streptavidin antibody (HRP)
• Species/Host: Rabbit
• Clonality: Polyclonal
• Tested applications: ELISA, WB
• Reactivity: Bacteria
• Isotype: IgG
• Immunogen: Streptavidin [Streptomyces avidinii]
• Concentration: 10.0 mg/mL
• Dilution range: ELISA: 1:20,000-1:100,000, WB: 1:1000
• Form/Appearance: Lyophilized
• Purity: Streptavidin Antibody Peroxidase Conjugate 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-Peroxidase, anti-Rabbit Serum as well as purified and partially purified Streptavidin [Streptomyces avidinii]. No cross reactivity occurs against avidin.
• Conjugation: HRP
• Storage: 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.

• Note: For research use only
• Application notes: Anti-Streptavidin Peroxidase Conjugated Antibody has been tested by ELISA and western blot. This product is assayed against 1.0 ug of Streptavidin in a standard capture ELISA using ABTS (2,2’-azino-bis-[3-ethylbenthiazoline-6-sulfonic acid]) for 30 minutes at room temperature. Optimal concentrations in immunoassays should be determined by researcher.
• Expiration Date: 12 months from date of receipt.
