Specifications

Product Data

• Recommended Dilution: Suitable for Immunoblotting, ELISA, Immunohistochemistry, Immunomicroscopy as well as other antibody based assays using streptavidin or avidin conjugates requiring lot-to-lot consistency.
  Recommended Dilutions: This product has been assayed against 1.0 µg of Sheep IgG in a standard capture ELISA using Peroxidase Conjugated Streptavidin and ABTS (2,2'-azino-bis-[3-ethylbenthiazoline-6-sulfonic acid]) as a substrate for 30 minutes at room temperature. A working dilution of 1:40,000 to 1:160,000 of the reconstitution concentration is suggested for this product.
• Host: Rabbit
• Clonality: Polyclonal
• Immunogen: Sheep IgG F(ab')2 fragment
• Specificity: This product was prepared from monospecific antiserum by immunoaffinity chromato-graphy using Sheep IgG coupled to agarose beads followed by solid phase adsorption(s) to remove unwanted reactivities.
  Assay by immunoelectrophoresis resulted in a single precipitin arc against anti-biotin, anti-Rabbit Serum, Sheep IgG, Sheep IgG F(ab')2 and Sheep Serum.
  No reaction was observed against Sheep IgG F(c).
• Formulation: 0.02 M Potassium Phosphate, 0.15 M Sodium Chloride, pH 7.2 with 0.01% (w/v) Sodium Azide as preservative and 10 mg/ml Bovine Serum Albumin (BSA) (IgG and Protease free) as stabilizer.
  Label: Biotin
  State: Lyophilized purified Ig fraction.
  Label: Biotinamidocaproate N-Hydroxysuccinimide Ester (BAC)
  Molar radio: 10-20 BAC molecules per Rabbit IgG molecule.
• Reconstitution Method: Restore with 1.0 ml of deionized water (or equivalent).
• Concentration: 1.5 mg/ml (by UV absorbance at 280 nm)
• Purification: Immunoaffinity chromatography.
• Conjugation: Biotin
• Storage: Store vial at 4°C prior to restoration. For extended storage reconstitute product with 50% glycerol instead of water and then aliquot contents and freeze at -20°C or below.
  Centrifuge product if not completely clear after standing at room temperature.
  This antibody is stable for one month at 4°C as an undiluted liquid.
  Dilute only prior to immediate use.
  Avoid cycles of freezing and thawing.
