Perlecan (human) LANCE Ultra TR-FRET Detection Kit, 10,000 Assay Points

The LANCE® Ultra Human Perlecan Detection Kit is designed for detection and quantitation of human perlecan in buffered solution and 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.

Perlecan is a large (4391 AA) multidomain protein, one of them being Endorepellin (3687 – 4391 AA), synthesized primarily by vascular endothelial cells and deposited in the vascular extracellular matrix. Its function is to crosslink a variety of matrix components to maintain the endothelial barrier function. Further, it can stimulate growth and regeneration of the endothelium via the modulation of certain growth factor activities. Perlecan has garnered significant interest due to its ability to suppress tumor growth upon its own suppression. Also, its levels have been observed to decrease in other diseases like atherosclerosis and diabetes.
