The LANCE Ultra Mouse Leptin Detection Kit is designed for detection and quantitation of mouse leptin 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, leptin is a hormone that contains 146 amino acid residues and is secreted by differentiated adipocytes. It regulates energy homeostasis as a result of its action on the brain via hypothalamic neuronal pathways expressing the leptin receptor (LR). Hereditary deficiency of leptin, or functional LRs, causes severe obesity in humans and mice. Leptin mediated signaling has been implicated in the regulation of food intake, energy expenditure, lipid and carbohydrate metabolism, and reproductive, neuroendocrine, thyroid, and immune function.

The introduction of enzyme-linked immunosorbent assays (ELISAs) in the early 1970’s offered researchers a non-radiometric immunoassay platform without compromising sensitivity. Over the last 50 years scientists have made huge strides in disease research and drug discovery and a demand for greater assay throughput and sensitivity has evolved. In response, more robust immunoassays have been developed to address some of the limitations of the standard, colorimetric ELISA.
Find out about the most common limitations of traditional ELISAs and how different ELISA alternative technologies address these limitations.
