Application

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

IgG2 and IgG4 deficiency is associated with IgA deficiency as found in patients of ataxia telangiectasia. Examination of the distribution pattern of IgG subclasses in different types of diseases may provide insight into the immunological processes involved and thus may assist in the diagnosis of various disorders. IgG subclass expression pattern in malaria patients reveals positive association of IgG4 levels and malaria antigens but not with patients age.

General description

Monoclonal Anti-Human IgG4 (mouse IgG1 isotype) is derived from the HP-6025 hybridoma produced by the fusion of mouse myeloma cells and splenocytes from an immunized mouse. IgG4 is a subclass of IgG with γ4 heavy chain.

Immunogen

Purified human IgG4 myeloma proteins covalently coupled to polyaminostyrene (PAS) microbeads

Physical form

Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 15 mM sodium azide.

Specificity

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