The LANCE Ultra Mouse IL-6 Detection Kit is designed for detection and quantitation of murine IL-6 in cell culture media using a homogeneous TR-FRET (no-wash steps, no separation steps) assay.

The 500 point kit contains enough reagents to run 500 wells in 384-well format, using a 20 µL reaction volume (15 µL of sample). The 10,000 point kit contains enough reagents to run 10,000 wells in 384-well format, using a 20 µL reaction volume (15 µL of sample).

• No-wash steps, no separation steps
• TR-FRET technology
• Sensitive detection
• High reproducibility
• Faster time-to-results
• Easy automation
• 96-well, 384-well, and 1536-well formats

LANCE and LANCE (Lanthanide chelate excite) Ultra are our TR-FRET (time-resolved fluorescence resonance energy transfer), homogeneous (no wash) technologies. One antibody of interest is labeled with a donor fluorophore (a LANCE Europium chelate) and the second molecule is labeled with an acceptor fluorophore (ULight^™ dye). Upon excitation at 320 or 340 nm, energy can be transferred from the donor Europium chelate to the acceptor fluorophore if sufficiently close for FRET (~10 nm). This results in the emission of light at 665 nm.

In the mouse, Interleukin 6 (IL6) is a 187 amino acid cytokine. In humans, IL6 is produced by a variety of cell types, including T-cells, mast cells, and monocytes. IL6 signals through binding to the gp130/ IL6R receptor complex. IL6 acts not only on the immune system, but also affects many physiological events in various organs. IL6 exerts pro- or antiinflammatory responses, depending on the target cell analyzed and the in vivo environmental circumstances. IL6 is a differentiation and proliferation factor for B and T cells, and acts as a migration factor on monocytic cells. It is the major activator of acute-phase protein expression in the liver and acts as a survival factor on neuronal cells. Elevated serum IL6 levels have been observed during bacterial and viral infection, trauma, autoimmune disease, inflammation, and cancer.
