AlphaLISA Human IL-17A Biotin-Free Detection Kit is designed for the quantitative detection of human IL-17A 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.

Features and Benefits:
Human Interleukin 17 (IL17 or IL17A) is a homodimer formed of two ~15 kDa subunits produced by a subset of T helper cells named Th17. It is a proinflammatory cytokine that enhances T cell priming and stimulates macrophages, fibroblasts, endothelial and epithelial cells to produce multiple mediators of inflammation like IL1, IL6, TNF-α, NOS-2, metalloproteases, and chemokines. IL17 has been implicated in the proinflammatory patterns associated with joint inflammation and rheumatoid arthritis (RA) in mouse and human models. It is also critical for neutrophil activation and migration, and induces IL8, a key chemokine for neutrophils. IL17 signals through IL17R, which in mice has at least two members, IL17RA, and IL17RC. Recent studies suggest that the IL17 pathway may be a novel therapeutic target for the treatment of chronic inflammatory diseases like asthma and RA.
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.

The introduction of enzyme-linked immunosorbent assays (ELISAs) in the early 1970’s offered researchers a non-radiometric immunoassay platform without compromising sensitivity. Over the last 50 years scientists have made huge strides in disease research and drug discovery and a demand for greater assay throughput and sensitivity has evolved. In response, more robust immunoassays have been developed to address some of the limitations of the standard, colorimetric ELISA.
Find out about the most common limitations of traditional ELISAs and how different ELISA alternative technologies address these limitations.
Breast cancer tumors can adapt to immune cell infiltration by responding to the increased concentration of interferon gamma (IFN-ɣ) and other cytokines secreted by subsets of T lymphocytes with the upregulation of the immune checkpoint proteins such as Programmed cell death ligand 1 (PD-L1). These checkpoint proteins allow the tumors to evade immune targeting and reduce the immune response, thus promoting tumor progression.

Various cytokines are secreted during an active immune response that can have modulatory effects on target cell populations, including interferon gamma (IFN-ɣ), tumor necrosis factor alpha (TNFa) and several interleukins.
