Description

General description

IgG4 (Immunoglobulin G4) is produced by T helper 2 cytokines. Unlike other immunoglobulin G is rare and constitutes to only 3-4 percent of the total IgG in the serum.

Specificity

Monoclonal Anti-Human IgG4 is specific for the IgG4 subclass and nonreactive with IgG1, IgG2 and IgG3 in an ELISA.

Application

Monoclonal Anti-HuIgG4 man antibody produced in mouse has been used in ELISA and immunofluorescence.

The IUIS/WHO2 study singled out this monoclonal antibody as one of the most widely applicable IgG4 specific monoclonal antibodies. Monoclonal Anti-Human IgG4 may be used for the identification of the IgG4 subclass by various immunoassays including: ELISA, Imprint Immunofixation (IIF), Immunofluorometric Assay (IFMA), Hemagglutination (HA), Hemagglutination Inhibition (HAI), Particle Counting Immunoassay (PACIA), and detection of cytoplasmic IgG.

Biochem/physiol Actions

IgG4 (Immunoglobulin G4) antibody has reduced affinity for C1q (first component of complement q) and hence its anti-inflammatory activity differing from that of the other IgG subclasses. IgG4 antibodies are known to actively interchange Fab arms with another molecule, resulting in recombined antibodies with two different binding specificities. This exchange is considered as an important biological mechanism that contributes to its anti-inflammatory activity. IgG4 antibodies are normally noninflammatory, but autoreactive IgG4 antibodies are known to be associated with Immunoglobulin G4 (IgG4)-related disease (IgG4-RD), characterized by infiltrating lymphoplasmacytic cells and elevated serum IgG4. Increased levels of IgG4 is observed in atopic dermatitis, parasitic diseases, pemphigus vulgaris and pemphigus foliaceus.
