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%).

Specificity

The antibody reacts with the heavy chains of human IgG and with the light chains common to most human immunoglobulins.

Immunogen

Prepared from purified human IgG.

Application

EIA: 1:20,000-1:400,000 using enzyme-streptavidin conjugate.
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.

This Goat anti-Human IgG Antibody, biotin conjugate is validated for use in ELISA, WB for the detection of Human IgG.

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.

Storage and Stability

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.

Antibodies mediate effector functions through Fcγ receptor (FcγR) interactions and complement activation, causing cytokine release, degranulation, phagocytosis, and cell death. They are often undesired for development of therapeutic antibodies where only antigen binding or neutralization would be ideal. Effector elimination

Serological markers of Nuromyelitis Optica (NMO), an autoimmune disorder of the central nervous system, are autoantibodies targeting the astrocytic water channel aquaporin-4 (AQP4). We have previously demonstrated that the main epitopes for these autoantibodies (AQP4-IgG) are generated by the supramolecular
