Product Summary

The Quantikine Human IL-33 Immunoassay is a 4.5 hour solid phase ELISA designed to measure IL-33 in cell culture supernates, cell lysates, serum, and plasma. It contains E. coli-expressed recombinant human IL-33 and antibodies raised against the recombinant factor. This immunoassay has been shown to accurately quantitate recombinant human IL-33. Results obtained using natural human IL-33 showed linear curves that were parallel to the standard curves obtained using the Quantikine kit standards. These results indicate that this kit can be used to determine relative mass values for natural human IL-33.

Precision

Intra-Assay Precision (Precision within an assay) Three samples of a known concentration were tested on one plate to assess intra-assay precision
Inter-Assay Precision (Precision between assays) Three samples of a known concentration were tested in separate assays to determine inter-assay precision. Assays were performed by at least three technicians using two lots of kit components

Recovery

The recovery of human IL-33 spiked to levels throughout the range of the assay in various matrices was evaluated.

Sample Type Average % Recovery Range %
Cell Culture Media (n=4) 95 81-106
EDTA Plasma (n=4) 86 82-92
Heparin Plasma (n=4) 84 80-90
Serum (n=4) 96 88-103

Linearity

To assess the linearity of the assay, samples containing and/or spiked with high concentrations of human IL-33 were serially diluted with the appropriate Calibrator Diluent to produce samples with values within the dynamic range of the assay. Samples were diluted prior to assay.

Background: IL-33

IL-33 (Interleukin-33) is released from physically damaged or necrotic cells. It triggers Th2-biased immune cell activation at sites of inflammation as well as regulatory T cell and M2 macrophage expansion. It additionally induces angiogenesis, promotes tumor cell migration and invasion, limits cardiac myocyte hypertrophy, and limits the development of atherosclerotic plaques. IL-33 signals through a receptor complex composed of ST2 and IL-1 RAcP. IL-1 RAcP also associates with IL-1 RI, IL-1 RII, IL-1 R6, and SCF R/c-kit. Soluble isoforms of ST2 and IL-1 RAcP function as decoy receptors that regulate IL-33 bioactivity.

Assay Procedure

Refer to the product for complete assay procedure.

Bring all reagents and samples to room temperature before use. It is recommended that all samples, standards, and controls be assayed in duplicate.
  1.   Prepare all reagents, standard dilutions, and samples as directed in the product insert.
  2.   Remove excess microplate strips from the plate frame, return them to the foil pouch containing the desiccant pack, and reseal.
    3. 100 µL Assay Diluent
  3.   Add 100 µL of Assay Diluent to each well.
    4. 100 µL Standard, Control, or Sample
  4.   Add 100 µL of Standard, control, or sample to each well. Cover with a plate sealer, and incubate at room temperature for 2 hours on a horizontal orbital microplate shaker.
  5.   Aspirate each well and wash, repeating the process 3 times for a total of 4 washes.
    6. 200 µL Conjugate
  6.   Add 200 µL of Conjugate to each well. Cover with a new plate sealer, and incubate at room temperature for 2 hours on the shaker.
  7.   Aspirate and wash 4 times.
    8. 200 µL Substrate Solution
  8.   Add 200 µL Substrate Solution to each well. Incubate at room temperature for 30 minutes on the benchtop. PROTECT FROM LIGHT.
    9. 50 µL Stop Solution
  9.   Add 50 µL of Stop Solution to each well. Read at 450 nm within 30 minutes. Set wavelength correction to 540 nm or 570 nm.
