Product Summary for Human IL-11 Quantikine ELISA Kit

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.

Recovery for Human IL-11 Quantikine ELISA Kit

The recovery of human IL-11 spiked to three different levels throughout the range of the assay in various matrices was evaluated.

Sample Type Average % Recovery Range %
Cell Culture Media (n=5) 98 90-108
Citrate Plasma (n=5) 105 96-118
EDTA Plasma (n=5) 103 97-110
Heparin Plasma (n=5) 103 93-114
Serum (n=5) 99 89-117

Linearity

To assess the linearity of the assay, five samples were spiked with high concentrations of IL-11 in various matrices and diluted with the appropriate Calibrator Diluent to produce samples with values within the dynamic range of the assay.

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.
