The AlphaLISA® immunoassay kit for porcine TNFα enables the detection and quantitation of porcine TNFα in porcine serum, plasma, and, cell lysyate, cell culture supernatants using a homogeneous AlphaLISA assay (no wash steps). The assay shows minimal cross-reactivity with human and bovine TNFα and no cross reactivity towards porcine IFNγ.
For research use only; not for diagnostic procedures. All products to be used in accordance with applicable laws and regulations including without limitation, consumption & disposal requirements under European REACH regulations (EC 1907/2006).

Tumor necrosis factor alpha (TNFα) belongs to the TNF Superfamily and is primarily produced by activated macrophages. The primary role of TNFα is the regulation of immune cells. In porcine, TNFα is a pro-inflammatory cytokine that is involved in a multitude of pathological states such as influenza, coronavirus, tuberculosis, acute viral respiratory diseases, and response to vaccination. This kit is designed to detect TNFα in porcine serum, plasma, cell culture supernatants, cell lysates, and tissue homogenates.
AlphaLISA technology allows the detection of molecules of interest in a no-wash, highly sensitive, quantitative assay. In an AlphaLISA assay, a biotinylated anti-analyte antibody binds to the Streptavidin-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.
