Description

The FastScan Total E-Cadherin ELISA Kit is a sandwich enzyme-linked immunosorbent assay (ELISA) that detects endogenous levels of E-cadherin. To perform the assay, sample is incubated with a capture antibody conjugated with a proprietary tag and a second detection antibody linked to HRP, forming a sandwich with E-cadherin in solution. This entire complex is immobilized to the plate via an anti-tag antibody. The wells are then washed to remove unbound material. TMB is then added. The magnitude of observed signal is proportional to the quantity of E-cadherin.

*Antibodies in this kit are custom formulations specific to kit.

Specificity/Sensitivity

The FastScan Total E-Cadherin ELISA Kit detects endogenous levels of E-cadherin as shown in Figure 1. This kit detects proteins from the indicated species, as determined through in-house testing, but may also detect homologous proteins from other species.

Background

Cadherins are a superfamily of transmembrane glycoproteins that contain cadherin repeats of approximately 100 residues in their extracellular domain. Cadherins mediate calcium-dependent cell-cell adhesion and play critical roles in normal tissue development (1). The classic cadherin subfamily includes N-, P-, R-, B-, and E-cadherins, as well as about ten other members that are found in adherens junctions, a cellular structure near the apical surface of polarized epithelial cells. The cytoplasmic domain of classical cadherins interacts with β-catenin, γ-catenin (also called plakoglobin), and p120 catenin. β-catenin and γ-catenin associate with α-catenin, which links the cadherin-catenin complex to the actin cytoskeleton (1,2). While β- and γ-catenin play structural roles in the junctional complex, p120 regulates cadherin adhesive activity and trafficking (1-4). Investigators consider E-cadherin an active suppressor of invasion and growth of many epithelial cancers (1-3). Research studies indicate that cancer cells have upregulated N-cadherin in addition to loss of E-cadherin. This change in cadherin expression is called the "cadherin switch." N-cadherin cooperates with the FGF receptor, leading to overexpression of MMP-9 and cellular invasion (3). Research studies have shown that in endothelial cells, VE-cadherin signaling, expression, and localization correlate with vascular permeability and tumor angiogenesis (5,6). Investigators have also demonstrated that expression of P-cadherin, which is normally present in epithelial cells, is also altered in ovarian and other human cancers (7,8).

    Figure 1. A-431 cells (E-cadherin positive) express high levels of E-cadherin compared to HeLa cells (E-cadherin negative). The relationship between lysate protein concentration from HeLa and A-431 cells and the absorbance at 450 nm using the FastScan Total E-Cadherin ELISA Kit #94249 is shown in the upper figure. The corresponding western blots using an E-cadherin antibody (left panel) and an α-actinin antibody as a loading control (right panel) are shown in the lower figure.
