The LANCE Ultra Mouse TNFα Detection Kit is designed for detection and quantitation of mouse tumor necrosis factor α 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 µL reaction volume (15 µL of sample). The 10,000 point kit contains enough reagents to run 10,000 wells in 384-well format, using a 20 µL reaction volume (15 µL of sample).
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.
In the mouse, Tumor Necrosis Factor alpha (TNFα) is primarily produced as a homotrimeric 235 amino acid membranebound protein. The soluble mature homotrimeric form of 156 amino acids is then released by the metalloprotease TNFα converting enzyme. In humans, TNFα is produced by many cell types like macrophages, monocytes, neutrophils, T cells, and NK cells. It causes cytolysis and cytostasis of many tumor cell lines in vitro. Within hours of injection, TNFα leads to the destruction of small blood vessels within malignant tumors. Although TNFα inhibits the growth of endothelial cells in vitro, it is a potent promoter of angiogenesis in vivo. In contrast to chemotherapeutic drugs, TNFα specifically attacks malignant cells. Furthermore, TNFα is associated with autoimmune disorders, and antibodies directed against TNFα have proven useful.
