Revvity IL-8 (human) LANCE Ultra TR-FRET Detection Kit; 500 assay points

Revvity The LANCE Ultra Human IL-8 Detection Kit is designed for detection and quantitation of human interleukin 8 in cell culture media using a homogeneous TR-FRET (no-wash steps, no separation steps) assay. The 500 point kit contains enough reagents to run 500 wells in 384-well format, using a 20 uL reaction volume (15 uL of sample). The 5,000 point kit contains enough reagents to run 5,000 wells in 384-well format, using a 20 uL reaction volume (15 uL of sample). 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. Interleukin 8 (IL8 or CXCL8), a member of the ELR+ CXC chemokine family, is a 8.4 kDa polypeptide that forms homodimers in vivo. IL8 is secreted by several types of cells: fibroblasts, monocytes, macrophages and endothelial cells, among many others, in response to inflammatory stimuli. It is a chemoattractant and activator for neutrophils, directing them from periferal blood to the site of inflammation. It is also a potent angiogenic factor promoting endothelial and epithelial migration and proliferation in several cancers, and is associated with metastasis. It signals through two specific G protein-coupled receptors, CXCR1 and CXCR2, sharing 77% identity. - PEMSD
