Revvity Tnf (H) Lance Ultra Tr-F

Revvity The LANCE^® Ultra Human TNFα Detection Kit is designed for detection and quantitation of human TNFα in cell culture media using a homogeneous TR-FRET (no-wash steps, no separation steps) assay. - REVPFZ (Additional S&H Or Hazmat Fees May Apply)

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

Revvity 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. - REVPFZ (Additional S&H Or Hazmat Fees May Apply)

Revvity Tumor necrosis factor alpha (TNFα) 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. TNFα 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. - REVPFZ (Additional S&H Or Hazmat Fees May Apply)
