Descripción

General description

IgG4 (Immunoglobulin G4) is produced by T helper 2 cytokines.

Specificity

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

Application

Monoclonal Anti-Human IgG4-FITC antibody produced in mouse has been used in immunohistofluorescence and immunofluorescence assay.

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 differs 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.

Physical form

Solution in 0.01 M phosphate buffer, pH 8.0, containing 1% inactivated bovine serum albumin and 15 mM sodium azide.
