Analysis Note
The total protein is measured by absorbance (A280nm). Antibody titer is standardized by equivalence-point precipitation. Each affinity purified antibody is tested for purity at 10 mg/mL using immunoelectrophoresis. The product is goat IgG; no trace of albumin is detected.
Preparation Method
The affinity purified antibody is prepared from the specific goat IgG fraction by solid phase absorption. The resulting affinity purified antibody 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, and vialed. No preservative has been added.
Applications
Goat affinity purified antibody to human IgG Fc is used as a precipitating antibody. It gives sharp precipitin lines in immunoelectrophoresis and immunodiffusion techniques. It is suitable for conjugation with enzymes, radiolabels, fluorochromes or other markers, and for attachment to solid supports for use as an immunoadsorbant. It is also suitable for use as a primary reagent in enzyme immunoassays, fluorescein immunoassays and blot, cell or tissue immunostaining. These affinity purified antibodies are recommended to avoid non-specific binding from the inherent antibodies of host animals. (Note: F(ab')2 fragments are recommended for staining of cells or tissues which contain Fc receptors).
