Peroxidase-Conjugated Goat IgG Fraction to Rabbit IgG (Whole

Analysis Note The total protein is measured using the Biuret procedure with bovine albumin as the standard. To ensure that the product titer falls within the required range, antibody titer is standardized by microtiter plate ELISA with rabbit IgG. The product is tested for purity and specificity at final concentration by immunoelectrophoresis. The antibody is predominantly goat IgG; no trace of albumin is detected. Preparation Method Antibody and highly purified HRP (Rz>3.0) are conjugated under defined conditions to obtain optimally labeled product. Conjugated protein is purified by salt fractionation. The product is dialyzed into 0.02M sodium phosphate, 0.14M sodium chloride, pH 7.3, adjusted to standard titer, filtered through a 0.22 µm filter, vialed and lyophilized. Applications Peroxidase-conjugated goat IgG fraction to rabbit IgG (whole molecule) product is suitable for use as a reagent in enzyme immunoassays (EIA), cell and tissue staining (for light microscopy), cell and tissue labeling (for electron microscopy), and blot immunostaining. Note: F(ab')2 fragments are recommended for staining of cells or tissues which contain Fc receptors. Affinity purified antibodies or their fragments are recommended to avoid non-specific binding from inherent antibodies of host animals. Product Overview Specificity for human IgG is determined by immunoelectrophoresis (IEP) versus purified human IgA, IgG, IgM, Bence Jones kappa, and Bence Jones lambda myeloma proteins.Identity and purity of the antibody is established by immunoelectrophoresis (IEP), prior to conjugation. Electrophoresis of the antibody preparation followed by diffusion versus anti-goat IgG and anti-goat whole serum result in single arcs of precipitation in the gamma region. Product Description Peroxidase-conjugated goat igg fraction to rabbit igg (whole molecule) is the lyophilized powder of horseradish peroxidase (HRP)-conjugated goat IgG fraction to rabbit IgG (whole molecule) and buffer salts. Anti-Human IgG is developed in goat using IgG from pooled normal human serum as the immunogen. Whole antiserum is fractionated and then further purified by ion exchange chromatography to provide the IgG fraction of antiserum. This fraction is essentially free of other goat serum proteins. Recommended Use RECONSTITUTION: Reconstitute product with 2.0 mL of deionized or distilled water. Gentle swirling may be used to speed rehydration. Do not add sodium azide. Avoid vigorous shaking of the reconstituted material. Typical Working Concentration Anti-Human IgG (whole molecule)-HRP antibody is suitable for use in direct immunofluorescence (1:16), as well as for ANA-indirect immunofluorescence at 1:32 or 1:641 dilutions. The antibody may also be used in FACS-based assays (1:200).
