General description

Human IgG consists of four subclasses (1-4) that can be recognized by antigenic differences in their heavy chains. It constitutes approximately 65, 30, 5 and 4% of the total IgG, respectively. Each subclass has different biological and physiochemical properties. The IgG subclass may be preferentially produced in response to different antigens and pathological conditions. Only IgG1 and IgG3 are capable of adhering to mononuclear phagocytes while IgG2 and IgG4 auto-antibodies are not associated with disorders such as hemolytic anemia.Serum IgG subclass deficiencies have been recorded for different patient groups. For example, IgG2 and IgG4 deficiency is associated with IgA deficiency as found in patients of ataxia telangiextasia. 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. For example IgG subclass expression pattern in malaria patients reveals positive association of IgG4 levels and malaria antigens but not with patients age.Monoclonal Anti-Human IgG4 specifically recognizes Human IgG4. The antibody shows no cross-reactivity with human IgG1, IgG2 and IgG3. The IUIS/WHO study evlauted this monoclonal antibody as one of the most widely applicable IgG4 specific monoclonal antibodies


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


The antibody is recommended to use in various immunological techniques, including ELISA.

Serum IgG subclass levels were determined using a competitive indirect immunoenzymatic assay with monoclonal antibodies in 16 patients with ataxia-telangiectasia. Eight children had IgA deficiency, two had IgG and IgA deficiency and six patients showed no immunoglobulin class abnormality. However...

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...

Seventy-four monoclonal antibodies (McAb) of putative specificity for human IgG (11), the IgG sub-classes (59) or Gm allotypes (4) have been evaluated for reactivity and specificity in eight laboratories employing different assay techniques or protocols. For the IgG, IgG3, IgG4...
Antibody-based serology tests are useful in identifying subjects with an adaptive immune response to the SARS-CoV-2 virus. Anti-human immunoglobulin antibodies allow for quick and simple, yet reliable assays with easy readouts and can also be adapted for high-throughput screening.
