LANCE Ultra Human E-Cadherin Detection Kit, 500 Assay Points

The LANCE^® Ultra Human E-cadherin Detection Kit is designed for detection and quantitation of human insulin in cell culture media and cell lysates 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.

Epithelial Cadherin (E-Cadherin), also known as Cadherin-1 or Uvomorulin (in mouse and rat) is a single-pass transmembrane protein that facilitates calcium dependent cell adhesion. A member of the Cadherin family, E-Cadherin utilizes five extracellular EC domains to form cis-clusters between adjacent epithelial cells and trans-clusters within the same cell. Cleavage of the N-terminal domain by a number of proteases is critical for cell motility and EGFR-dependent survival. The intracellular domain of E-cadherin interacts with many proteins including β-catenin, α-catenin, vinculin, and plakoglobin. Lack of binding to any of these proteins has been indicated in cancer metastasis.
