Product specifications

Intended use

This ELISA PathRF kit is intended for the quantification of human IFN-γ in serum and plasma containing rheumatoid factor (RF). For research use only. Not for use in diagnostic procedures.

Serum/Plasma samples

ELISA PathRF kits
ELISA PathRF kits are designed to eliminate potential interference from RF and heterophilic antibodies. The combination of a recombinant detection mAb and RF-block diluent prevents RF and heterophilic antibodies from cross-linking the assay antibodies, effectively reducing the risk of false-positive signal. RF and heterophilic antibodies can be found at high concentrations in serum and plasma from individuals with autoimmune diseases such as rheumatoid arthritis. The kit has been validated with RF-containing plasma.

Analyte description

Interferon-γ (IFN-γ) is the only type II interferon. This proinflammatory cytokine is secreted by activated T cells and NK cells. It activates macrophages and endothelial cells and regulates immune responses by affecting APCs, T cells, and B cells. Production of IFN-γ by helper T cells and cytotoxic T cells is a hallmark of the Th1-type phenotype. Thus, high-level production of IFN-γ is typically associated with effective host defense against intracellular pathogens.
