General description

IgG is the main antibody type found in plasma and extracellular fluid and is expressed on B cell membrane. IgG is further subdivided into four subclass- IgG1, IgG2, IgG3 and IgG4 and contribute 65, 30, 5 and 4% in total IgG. IgG2 produce in response to anti-polysaccharide. Monoclonal anti-human IgG2 (Fc specific) antibody can be used in indirect ELISA and Immunofluorometric Assay (IFMA). Mouse anti-human IgG2 (Fc specific) antibody reacts specifically with IgG2 of human but not with other IgG subclasses.

Specificity

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

Immunogen

Purified human IgG myeloma proteins covalently linked to polyaminostyrene microbeads.

Application

Monoclonal anti-human IgG2 (Fc specific) antibody can be used to detect IgG2 subclass by using different immunoassays like- hemagglutination (HA), hemagglutination inhibition(HAI), Imprint Immunofixation (IIF) and Particle Counting Immunoassay (PACIA). It can also be used in immunohistological assays.
Monoclonal Anti-Human IgG2 (Fc specific) antibody is suitable for use in ELISA.

Biochem/physiol Actions

IgG2 immunoglobulin is a 146 kDa IgG subtype, which mediates immune response to the polysaccharide antigens of the bacterial capsule. Deficiency of IgG2 poses an increased risk to certain bacterial infections. IgG2 has the least affinity among the IgG subtypes to Fcγ receptors (FcγR). IgG2 exists in three forms namely, IgG2-A, -B, and -A/B. They show variation in the arrangement of fragment antigen binding domain (Fab) and hinge region.

Physical form

This product is provided as ascites fluid with 15 mm sodium azide as a preservative.

Storage and Stability

For continuous use, store at 2-8 °C for up to one month. For extended storage, the solution may be frozen in working aliquots. Repeated freezing and thawing is not recommended. Storage in "frost-free" freezers is not recommended. If slight turbidity occurs upon prolonged storage, clarify the solution by centrifugation before use.

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.
