The LANCE® Ultra Human IL-1RA Detection Kit is designed for detection and quantitation of human interleukin-1RA in buffered solution and cell culture media using a homogeneous TR-FRET (no-wash steps, no separation steps) assay.
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.
Interleukin-1 Receptor Antagonist (IL1RA) is a member of the interleukin-1 cytokine family. Immune, epithelial, and adipose cells secrete IL1RA which will bind to the interleukin-1 receptor and inhibit pro-inflammatory signaling through IL-1α and IL-1β. Studies have shown that IL1RA plays a key role in suppressing the pro-inflammatory effects of IL-1 in diseases like rheumatoid arthritis. Additionally, it has been observed that IL1RA may play an important role in diseases like osteoporosis where IL1RA levels are suppressed compared to controls. Furthermore, it has been observed that IL-1 cytokines are abundantly present at tumor sites and the addition of IL1RA can suppress growth of IL-1 producing tumors.

The introduction of enzyme-linked immunosorbent assays (ELISAs) in the early 1970’s offered researchers a non-radiometric immunoassay platform without compromising sensitivity. Over the last 50 years scientists have made huge strides in disease research and drug discovery and a demand for greater assay throughput and sensitivity has evolved. In response, more robust immunoassays have been developed to address some of the limitations of the standard, colorimetric ELISA.
Find out about the most common limitations of traditional ELISAs and how different ELISA alternative technologies address these limitations.
This manual explains how to run the LANCE Ultra human IL-1RA detection assay.
