IFNγ (human) AlphaLISA Biotin-Free Detection Kit, 500 Assay Points

The AlphaLISA Human IFNγ Biotin-Free Detection Kit is designed for the quantitative detection of human IFNγ in serum, cell culture medium, and other samples types using a homogeneous (no wash steps, no separation steps) assay. The biotin-free kit uses anti-DIG (anti-Digoxin) Donor beads instead of streptavidin Donor beads, which makes the kit compatible with high-biotin culture media and other sample types that contain high levels biotin (including brain/liver tissue extracts, milk and eggs).

Interferons (IFNs) activity has been discovered due to their antiviral effects. In humans, there are three families of IFNs: IFN type I (IFN-α, β, ω, ε, and κ), IFN type II (one single representative, IFN-γ), and IFN type III (IFN-λ1-3). Antigens and mitogens stimulate in Natural Killer (NK) and activated helper T lymphocytes (Th1) the production of IFN-γ. Human IFN-γ is a 140 amino acids polypeptide that shows multiple effects; it induces the production of cytokines, upregulates the expression of class I and II MHC antigens, and leukocyte adhesion molecules. It also activates macrophages, enhances the secretion of immunoglobulins by B cells, and potentiates Th1 cell expansion. Response to IFN-γ is mediated by the heterodimeric IFN-γ Receptor, triggering a signaling cascade involving JAK1, JAK2, and STAT1. Importantly, IFNs have been proved to be effective in the treatment of several viral infections and cancers.

AlphaLISA technology allows the detection of molecules of interest in a no-wash, highly sensitive, quantitative assay. In an AlphaLISA biotin-free assay, a DIG-labeled anti-analyte antibody binds to the anti-DIG-coated Donor beads while another anti-analyte antibody is conjugated to AlphaLISA Acceptor beads. In the presence of the analyte, the beads come into close proximity. The excitation of the Donor beads causes the release of singlet oxygen molecules that triggers a cascade of energy transfer in the Acceptor beads, resulting in a sharp peak of light emission at 615 nm.
