Revvity TNF? (human) LANCE Ultra TR-FRET Detection Kit

Revvity The LANCE Ultra Human TNF Detection Kit is designed for detection and quantitation of human TNF in cell culture media using a homogeneous TR-FRET (no-wash steps, no separation steps) assay. 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. Tumor necrosis factor alpha (TNF) is a multifunctional proinflammatory cytokine synthesized mainly by nucleated blood cells as a 233 aa type II transmembrane protein which is cleaved by ADAM17 between aa 76-77 to form a soluble homotrimeric complex. TNF plays a role in lipid metabolism, coagulation, and endothelial function and has been associated with cancer, infection and inflammation (including inflammatory bowel disease), ischemia/reperfusion injury and heart failure, and insulin resistance. - PEMSD
