一般描述

IgG is present in large quantities in the human serum. It constitutes about 10-20% of the plasma proteins. IgG is composed of glycoproteins, out of which it is 82-96% proteins and 4-18% carbohydrates. It consists of four sub-classes i.e IgG1, IgG2, IgG3, and IgG4. IgG is composed of four polypeptide chains-two heavy chains (γ chains) and two light chains (κ or λ chains) which are linked by inter-chain disulfide bonds. The heavy chains consist of a N-terminal variable domain (VH) and three constant domains (CH1, CH2, CH3). A hinge region exists between the CH1 and CH2 region. The light chains have one N-terminal variable domain (VL) and one constant domain (CL). The heavy and the light chains are linked at VH and CH1 domain to form the Fab arm (Fragment antigen binding). The antigen binds to the V regions of the antibody.

应用

Anti-Human IgG (whole molecule) antibody has been used in

• enzyme linked immunosorbent assay (ELISA)
• printing and processing of reverse phase protein microarrays
• western blot
• radial immunodiffusion

生化/生理作用

IgG, a monoclonal antibody can be cleaved at the hinge region by nonspecific proteases like papain and pepsin. This can result in univalent Fab fragments or bivalent F(ab′)₂fragments. These two enzymes have a broad substrate specificity resulting in heterogenous fragments.
IgG antibody subtype is the most abundant serum immunoglobulin of the immune system. It is secreted by B cells and is found in blood and extracellular fluids and provides protection from infections caused by bacteria, fungi and viruses. Maternal IgG is transferred to fetus through the placenta that is vital for immune defense of the neonate against infections.

外形

Anti-Human IgG is supplied as a liquid containing 15 mM sodium azide as a preservative

储存及稳定性

For continuous use, store at2-8 ℃. For extended storage, the solution may be frozen in working aliquots. Repeated freezing and thawing, or storage in "frost-free" freezers,is not recommended. If slight turbidity occurs upon prolonged storage, clarify the solution by centrifugation before use.
