Description
General description
IgG is a monomeric immunoglobulin, consists of two heavy chains (gamma chains) and two light chains. Each molecule has two antigen binding sites. IgG is the most abundant immunoglobulin. It is approximately equally distributed in blood and in interstitial fluid, constituting 75% of serum immunoglobulins in humans. This is the only isotype that can pass through the human placenta, providing protection to the fetus in its first weeks of life before its own immune system has developed. There are 4 subclasses: IgG1 (66%), IgG2 (23%), IgG3 (7%) and IgG4 (4%).
Immunogen
Prepared from purified human IgG.
Application

Western blots: 1:20,000-1:400,000 using enzyme-streptavidin conjugate.
Immunohistochemistry: 1:500-1:5,000 using enzyme-streptavidin conjugate.
Flow cytometry: 1:200-1:1,000.
Fluorescence Immunohisto/cytochemistry: 1:200-1:1,1000.
Optimal working dilutions must be determined by the end user.

Research Sub Category
Whole Immunoglobulin Secondary Antibodies
This Goat anti-Human IgG Antibody, biotin conjugate is validated for use in ELISA, WB for the detection of Human IgG.
Biochem/physiol Actions
The antibody reacts with the heavy chains of human IgG and with the light chains common to most human immunoglobulins.
Physical form
ImmunoAffinity Purified
Purified by immunoaffinity chromatography using antigen coupled to agarose beads. Lyophilized. Buffer is 0.01 M Sodium Phosphate, 0.25 M NaCl, pH 7.6 with 15 mg/mL BSA, and 0.05% sodium azide.
Preparation Note
Maintain lyophilized product at 2°-8°C for up to 12 months from date of receipt. After reconstitution the product is stable for six weeks at 2°-8°C as an undiluted liquid. Reconstitute vial with 2 mL of distilled water. For extended storage after reconstitution, add an equal volume of glycerol to make a final concentration of 50% glycerol followed by storage at -20°C in undiluted aliquots for up to 12 months. Please note the concentration of antibody (and buffer salts) will decrease to one-half of the original after the addition of glycerol and final working dilutions must be adjusted accordingly. Avoid repeated freeze thaw cycles.
