The Human E-Cad (E-Cadherin) ELISA quantitates E-Cad in serum, plasma and other biological fluids.
原理方法
The Human E-Cadherin (E-Cad) solid-phase sandwich ELISA (enzyme-linked immunosorbent assay) is designed to measure the concentration of E-Cadherin (E-Cad) in biological samples. A target-specific antibody has been pre-coated in the wells of the supplied microplate. Samples, standards, or controls are added into these wells and bind to the immobilized (capture) antibody.
The sandwich complex is formed by the addition of a second (HRP-linked) detection antibody specific to E-Cadherin (E-Cad). Excess reagents are washed from the plate.
A substrate solution is added that reacts with the enzyme-antibody-target complex to produce a measurable signal. The enzyme-substrate reaction is terminated by the addition of stop solution. The intensity of the signal, measured spectrophotometrically at 450 ± 2 nm, is directly proportional to the concentration of E-Cadherin (E-Cad) present in the original specimen.
Rigorous validation:
Each manufactured lot of this ELISA kit is quality tested for criteria such as sensitivity, specificity, precision, and lot-to-lot consistency. See manual for more information on validation.

E-Cadherin (epithelial cadherin) is a classical cadherin from the cadherin (alcium dependent adhesion protein) superfamily. The encoded protein is a calcium dependent cell-cell adhesion glycoprotein comprised of five extracellular cadherin repeats, a transmembrane region and a highly conserved cytoplasmic tail. Mutations in this gene are correlated with gastric, breast, colorectal, thyroid and ovarian cancer. Loss of function is thought to contribute to progression in cancer by increasing proliferation, invasion, and/or metastasis. The ectodomain of this protein mediates bacterial adhesion to mammalian cells and the cytoplasmic domain is required for internalization. Identified transcript variants arise from mutation at consensus splice sites. E-cadherin plays a central role in the growth and development of cells by controlling tissue architecture, and maintenance of tissue integrity. In humans, E-cadherin is encoded by the CDH1 gene present on chromosome 16. Studies have demonstrated that reduction and/or loss of E-cadherin expression in carcinomas correlates positively with the potential of these tumors for invasion and metastasis.
