Product Summary

The Quantikine Human IL-11 Immunoassay is a 4.5-5.0 hour, solid-phase ELISA designed to measure IL-11 in cell culture supernates, serum, or plasma. It contains Sf 21-expressed recombinant human IL-11 and antibodies raised against recombinant human IL-11. This immunoassay has been shown to accurately quantitate the recombinant factor. Results obtained using natural human IL-11 showed dose curves that were parallel to the standard curves obtained using the recombinant Quantikine kit standards. These results indicate that this kit can be used to determine relative mass values for natural IL-11.


Intra-Assay Precision (Precision within an assay) Three samples of known concentration were tested on one plate to assess intra-assay precision

Background: IL-11

Interleukin-11, also known as AGIF, is a pleiotropic cytokine in the IL-6 family, which also includes LIF, CNTF, Oncostatin M, Cardiotrophin-1, IL-27, and IL-31. It is secreted by osteoblasts, synoviocytes, fibroblasts, chondrocytes, intestinal myofibroblasts, and trophoblasts. It is found in the plasma mainly during inflammation, and is considered to be primarily anti-inflammatory. It stimulates hematopoiesis and thrombopoiesis, regulates macrophage differentiation, and confers mucosal protection in the intestine. It has also been found to enhance T cell polarization toward Th2, promote B cell IgG production, increase osteoclast bone absorption, protect endothelial cells from oxidative stress, and regulate epithelial proliferation and apoptosis. IL-11 signals through a receptor complex that contains IL-11 R alpha and gp130. A soluble form of IL-11 R alpha can bind IL-11 and either form a signaling complex with gp130 on the cell surface or inhibit cell surface IL-11 R alpha/gp130 signaling.

  3. 100 µL Assay Diluent
  4.   Add 100 µL of Assay Diluent to each well.

  5. 100 µL Standard, control, or sample
  6.   Add 100 µL of Standard, control, or sample to each well. Cover with a plate sealer, and incubate at room temperature for 2 hours.
  7.   Aspirate each well and wash, repeating the process 3 times for a total of 4 washes.

  8. 200 µL Conjugate
  9.   Add 200 µL of Conjugate to each well, and cover with a new plate sealer.
  10.   For Serum & Plasma Samples:  Incubate at room temperature for 2 hours.
    For Cell Culture Supernate Samples:  Incubate at room temperature for 2.5 hours.
  11.   Aspirate and wash 4 times.

  12. 200 µL Substrate Solution
  13.   Add 200 µL Substrate Solution to each well. Incubate at room temperature for 30 minutes. PROTECT FROM LIGHT.
