Product Summary for Human E-Cadherin Quantikine ELISA Kit
The Quantikine™ Human E-Cadherin Immunoassay is a 4.5 hour solid-phase ELISA designed to measure human E-Cadherin in cell culture supernates, serum, plasma, saliva, and urine. It contains HEK293-expressed recombinant human E-Cadherin and has been shown to accurately quantitate the recombinant factor. Results obtained using natural human E-Cadherin showed linear curves that were parallel to the standard curves obtained using the Quantikine kit standards. These results indicate that this kit can be used to determine relative mass values for natural human E-Cadherin.

Background: E-Cadherin
E-Cadherin/Cadherin-1 (ECAD) Is a transmembrane cell adhesion protein. It forms homophilic clusters between epithelial cells and is a critical component of adherens junctions. These junctions are critical for the maintenance of the epithelial barrier and epithelial tissue homeostasis. Decreased E-Cadherin is associated with physiological and pathological epithelial-to-mesenchymal transition (EMT) and cell migration, and E-Cadherin loss contributes to cancer metastasis. The shed ECD is released as a soluble factor that enhances cancer cell motility and EGFR-dependent survival and proliferation.
