The Interferon-inducible protein 10 (IP-10) BioAssay(TM) ELISA Kit (Human) is a sandwich ELISA for the quantitative determination of human interferon-inducible protein 10 (IP-10) concentrations in serum, plasma, tissue homogenates. Sensitivity: 7.8pg/ml Detection Range: 31.25-2000pg/ml Specificity: This assay has high sensitivity and excellent specificity for detection of human IP-10. No significant cross-reactivity or interference between human IP-10 and analogues was observed. Precision: Intra-assay: CV%<8% Inter-assay: CV%<10% Test Principle: An antibody specific for IP-10 has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and any IP-10 present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for IP-10 is added to the wells. After washing, avidin conjugated Horseradish Peroxidase (HRP) is added to the wells. Following a wash to remove any unbound avidin-enzyme reagent, a substrate solution is added to the wells and color develops in proportion to the amount of IP-10 bound in the initial step. The color development is stopped and the intensity of the color is measured. Kit Components: Assay plate, 1x96wells Standard (Freeze dried), 2 Biotin-antibody (100X), 1x120ul HRP-avidin (100X), 1x120ul Biotin-antibody Diluent, 1x15ml HRP-avidin Diluent, 1x15ml Sample Diluent, 1x50ml Wash Buffer (25X), 1x20ml TMB Substrate, 1x10ml Stop Solution, 1x10ml Storage and Stability: Store powder at 4C liquid at -20C. Store other components at 4C. Stable for 6 months after receipt. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Assay Summary: 1.
