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.

Specificity

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

Immunogen

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

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.

Physical form

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

Several lines of evidence indicate that immunoglobulin-bound prolactin found in human serum is not a conventional complex between an anti-prolactin antibody and prolactin but a different type of association of prolactin with the Fab portion of IgG heavy chains. The...

It is traditionally held that human IgG4 MoAbs should not deplete target cells in vivo, as this isotype is inactive in a number of in vitro assays that measure effector function. We have previously challenged this dogma, and the current...

The anti-malarial IgG immune response during the lengthy and dry season in areas of low malaria transmission as in Eastern Sudan is largely unknown. In this study, ELISA was used for the measurement of pre-existing total IgG and IgG subclasses...
