AlphaLISA Biotin-Free Human TNFα Detection Kit, 500 Assay Points

The AlphaLISA® Human TNFα Biotin-Free Detection Kit is designed for the quantitative detection of human TNFα 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).

We now offer a new and improved High Performance version of the AlphaLISA Biotin Free Human TNF.

For research use only. Not for use in 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).

    • No-wash steps, no separation steps
    • Compatible with high biotin samples, including RPMI and high-biotin tissue extracts
    • ELISA alternative technology
    • Sensitive detection
    • Broad sample compatibility
    • Results in less than 3 hours

    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.
