Peroxidase-Conjugated Goat IgG Fraction to Human IgG (Whole Molecule)

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 human IgG. The product is tested for purity and specificity at final concentration by immunoelectrophoresis. 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, with 0.01% thimerosal, adjusted to standard titer, filtered through a 0.22 µm filter, vialed and lyophilized. Applications Peroxidase-Conjugated Goat IgG Fraction to Human IgG (Whole Molecule) has been used in dot blot. It is suitable for use as a reagent in enzyme immunoassays (EIA), cell and immunostaining of acetone-fixed frozen and formalin-fixed, paraffin-embedded tissue sections, 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 Description Peroxidase-Conjugated Goat IgG Fraction to Human IgG (Whole Molecule) is the lyophilized powder of horseradish peroxidase (HRP)-conjugated goat IgG fraction to human IgG (whole molecule) and buffer salts. Typical Working Concentration Direct ELISA: 1:30,000; dot blot: 1:80,000; immunohistochemistry (formalin-fixed, paraffin-embedded sections): 1:200. Dilution recommended: 1:500 - 1:4,000 for Tissue Staining; 1:1,000 - 1:8,000 for Immuno Blotting; 1:2,000 - 1:16,000 for ELISA/FIA
