General description

Monoclonal Anti-Human IgG1 (mouse IgG2a isotype) is derived from the hybridoma produced by the fusion of mouse myeloma cells and splenocytes from an immunized mouse. Human IgG consists of four subclasses (1-4) that can be recognized by antigen differences in their heavy chains. They constitute approximately 65, 25, 6 and 4% of the total IgG, respectively. Each subclass has different biological and physiochemical properties.
The antibody is specific for the Fc portion of human IgG1 and is non-reactive with other IgG subclasses. This clone, also described as HP-6091, was found to exhibit a valuable profile of reactivity and specificity for human IgG1 by the IUIS/WHO study.


Human IgG consists of four subclasses (1-4) that can be recognized.


Monoclonal Anti-Human IgG1 antibody produced in mouse has been used in:
  • direct hemagglutination(HA)
  • hemagglutination inhibition(HAI) assays
  • enzyme linked immunosorbent assay (ELISA)
  • immunofluorometric assay (IFMA)
  • immunofluorescence
  • cell-based assays for the detection of IgG subclasses of acetylcholine receptor (AChR) antibodies

Biochem/physiol Actions

Human IgG1 is the predominant subclass of in vivo and in vitro produced anti-tetanus toxoid antibodies. Only IgG1 and IgG3 are capable of adherence to mononuclear phagocytes via Fc receptors (FcR). A disproportionate elevation of IgG1 has also been found in the cerebral spinal fluid of patients with multiple sclerosis.

Physical form

The antibody is provided as ascites fluid with 0.1% sodium azide as a preservative.

Storage and Stability

For continuous use, store at 0-5 °C. 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 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.
