The LANCE® Ultra Human IL-28B Detection Kit is designed for detection and quantitation of human IL-28B 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 28B (IL28B), recently renamed interferon-λ 3 (IFNL3), is a cytokine encoded by the IL28 gene and is closely related to IL18A and IL29. IL28B plays a critical role in adaptive immune responses and regulates CD8+ T cell functions during vaccination. Clinically, it is involved in the protection from H1N1 viral infection and it can be used for predicting response to hepatitis C treatment with interferon and ribavirin. The present kit is designed to detect IL28B in human serum, plasma, and cell culture supernatants.
