The LANCE® Ultra Human IL-31 Detection Kit is designed for detection and quantitation of human IL-31 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 31 (IL31), a cytokine with a four-helix bundle structure, is produced by type 2 helper T cells and belongs to the IL6 cytokine family. Recently, several studies reported on prominent functions of the novel T-cell-derived pro-inflammatory cytokine IL31 and the levels in serum associated with patient having asthma, chronic inflammation, and skin diseases. Assaying for levels of IL31 can be used to measure and monitor the amount of inflammation and to guide inflammatory disease treatment.
