Uncoated Mouse CEACAM1 ( Carcinoembryonic Antigen Related Cell Adhesion Molecule 1 ) ELISA Kit (E-UNEL-M0178)

This ELISA kit uses the Sandwich-ELISA principle. The micro ELISA plate provided in this kit has been pre-coated with an antibody specific to CEACAM1 . Standards or samples are added to the micro ELISA plate wells and combined with the specific antibody. Then a biotinylated detection antibody specific for CEACAM1 and Avidin-Horseradish Peroxidase (HRP) conjugate are added successively to each micro plate well and incubated. Free components are washed away. The substrate solution is added to each well. Only those wells that contain CEACAM1 , biotinylated detection antibody and Avidin-HRP conjugate will appear blue in color. The enzyme-substrate reaction is terminated by the addition of stop solution and the color turns yellow. The optical density (OD) is measured spectrophotometrically at a wavelength of 450 nm ± 2 nm. The OD value is proportional to the concentration of CEACAM1 . You can calculate the concentration of CEACAM1 in the samples by comparing the OD of the samples to the standard curve.

CD66a,known as carcinoembryonic antigen-related cell adhesion molecule-1 (CEACAM-1),is a glycoprotein of the immunoglobulin superfamily and the carcinoembryonic antigen family.  CEACAM-1 functions as an intercellular adhesion molecule,an angiogenic factor,and a tumor cell growth inhibitor.  CEACAM-1 is expressed in multiple epithelial malignancies,including gastric cancer,colorectal cancer,and pancreatic cancer,as well as in NSC lung cancer and melanoma.  CEACAM-1 comprises one N-terminal variable domain,six C2-like Ig domains and glycosylphosphatidylinositol (GPI) linker,which facilitate adhesion through homophilic and/or heterophilic (CEACAM1–CEACAM5) interactions.  CEACAM-1 has a significant clinical role as a tumor marker for several tumors including gastrointestinal and respiratory malignancies.  CEACAM-1 has variable roles in tumor initiation,progression,and metastasis.
