Description
General description
Immunoglobulin IgG is an abundant protein in human serum. The four classes of IgG include IgG1, IgG2, IgG3 and IgG4.. The IgG heavy chain region is mapped to human chromosome 14. Immunoglobulin super-family have a common structure, comprising of two heavy (H) chains and two light (L) chains, held together by disulfide linkages. The heavy chain has one variable N-terminal region and three to four constant (CH1-CH4) C-terminal regions. The L chain comprises of one variable N-terminal region and a constant C-terminal region.
Application
Anti-Human IgG (Fc specific) Biotin antibody, Mouse monoclonal has been used in fluoroimmunoassay of plasma samples.
Applications in which this antibody has been used successfully, and the associated peer-reviewed papers, are given below.
Enzyme-linked immunosorbent assay (1 paper)
Monoclonal Anti-Human IgG (Fc specific)-Biotin antibody produced in mouse is suitable for ELISA at a working dilution of 1:80,000. It was used for labeling mouse splenocytes and analysis by flow cytometry.
Biochem/physiol Actions
IgG antibody subtype is the most abundant of serum immunoglobulins 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. The coupling of biotin to monoclonal Anti-Human IgG (Fc specific) antibody allows for the binding of various labels such as avidin or streptavidin.
IgG1 class is the most abundant and its deficiency results in hypogammaglobulinemia. IgG2 deficiency increases susceptibility to bacterial infections. IgG3 mediates effector functions, and IgG4 is associated with asymptomatic infection. Digestion of IgG by papain results in the generation of fragment antigen binding (Fab). Pepsin digestion of IgG generates fragment crystallisable (Fc). The Fc region of IgG antibody has enormous therapeutic potential and is exploited for the development of therapeutic antibodies.
The antibody is specific for the Fc portion of human IgG and recognizes an epitope common to all human IgG subclasses. This antibody was adopted as an Fc specific reagent in the IUIS/WHO study.
