• ELISA Kit Principle: The test principle applied in this kit is Sandwich enzyme immunoassay. The microtiter plate provided in this kit has been pre-coated with an antibody specific to Interleukin 18 (IL18). Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody specific to Interleukin 18 (IL18). Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added, only those wells that contain Interleukin 18 (IL18), biotin-conjugated antibody and enzyme-conjugated Avidin will exhibit a change in color. The enzyme-substrate reaction is terminated by the addition of sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450nm +/- 10nm. The concentration of Interleukin 18 (IL18) in the samples is then determined by comparing the O.D. of the samples to the standard curve.
• ELISA Kit Range: 15.6-1,000pg/mL
• ELISA Kit Recovery:

  Matrix	Recovery Range (%)	Average (%)
  serum(n=5)	85-104	95

• ELISA Kit Reproducibility: Intra-assay Precision (Precision within an assay): 3 samples with low, middle and high level Interleukin 18 (IL18) were tested 20 times on one plate, respectively. Inter-assay Precision (Precision between assays): 3 samples with low, middle and high level Interleukin 18 (IL18) were tested on 3 different plates, 8 replicates in each plate.

Target Info

• Gene Symbol: IL18
• Gene Full Name: interleukin 18
• Alias Symbols: iboctadekin;IFN-gamma-inducing factor;IGIF;IL-1 gamma;IL-18;IL1F4;IL-1g;Interferon gamma-inducing factor;interleukin 18 (interferon-gamma-inducing factor);interleukin-1 gamma;interleukin-18.
• NCBI Gene Id: 3606
• Protein Name: Interleukin-18
• Description of Target: A proinflammatory cytokine primarily involved in polarized T-helper 1 (Th1) cell and natural killer (NK) cell immune responses (Probable). Upon binding to IL18R1 and IL18RAP, forms a signaling ternary complex which activates NF-kappa-B, triggering synthesis of inflammatory mediators (PubMed:14528293, PubMed:25500532). Synergizes with IL12/interleukin-12 to induce IFNG synthesis from T-helper 1 (Th1) cells and natural killer (NK) cells (Probable) (PubMed:10653850).
