Immunoglobulin G (IgG) belongs to the immunoglobulin family and is a widely expressed serum antibody. An immunoglobulin has two heavy chains and two light chains connected by a disulfide bond. It is a glycoprotein and mainly helps in immune defense. IgG is usually found as a monomer. About 70 percent of the total immunoglobulin consists of IgG. Immunoglobulin G (IgG) participates in hypersensitivity type II and type III.
Human IgGs are glycoprotein antibodies that contain two equivalent light chains and a pair of identical heavy chains. IgGs have four distinct isoforms, ranging from IgG1 to IgG4. These antibodies regulate immunological responses to allergy and pathogenic infections. IgGs have also been implicated in complement fixation and autoimmune disorders . Monoclonal Anti-Human IgG (Fc specific) antibody detects the Fc portion, but not the Fab portion, of human IgG. Additionally, the antibody does not react with IgA, IgM, and immunoglobulin light chains.
Monoclonal Anti-Human IgG (Fc specific) antibody recognizes the fragment of crystallization (Fc) region of human immunoglobulin G (IgG) as determined by an enzyme-linked immunosorbent assay (ELISA).
Purified human IgG myeloma proteins covalently coupled to polyaminostyrene (PAS) microbeads
Monoclonal Anti-Human IgG (Fc specific) antibody has been used:
- to study the relationship between cell size, cell cycle and specific recombinant protein productivity
- in the label-free homogeneous assay to identify inhibitors of a4b7 integrin-mediated cell adhesion to mucosal addressin cell adhesion molecule (MadCAM)
- in enzyme-linked immunosorbent assay
Monoclonal Anti-Human IgG (Fc specific) antibody is suitable for use in indirect ELISA (1:5,000).
Acciones bioquímicas o fisiológicas
IgG (immunoglobulin G) antibody provides protection against bacterial, fungal and viral infections. The Fc (fragment crystallization tail) region of the antibody is implicated in complement activation in which it elicits an immune response by binding to the Fc receptor on macrophages. The Fc region also serves as a site for rheumatoid factor (autoantibody directed to Fc) attachment and protein A binding. A certain population of lymphocytes also possess a "Fc receptor". These functions indicate the importance of immunoreagents specific for the Fc fragment of Human IgG.

Almacenamiento y estabilidad
For continuous use, store at 0-5 ͦC. For extended storage, the solution may be frozen in working aliquots. Repeated freezing and thawing is not recommended. Storage in "frost-free" freezers is not recommended. If slight turbidity occurs upon prolonged storage, clarify the solution by centrifugation before use.
