The reaction between carcinoembryonic antigen and concanavalin A.

چکیده
The binding reaction between carcinoembryonic antigen (CEA) and concanavalin A (Con A) has been studied. CEA, prepared from liver métastasesin patients with carcinoma of the colon, was tested against Con A for precipitation. By using the techniques of immunodiffusion and counlerelectrophoresis, a precipitate line between CEA and Con A was observed, which was different from that seen between either Con A-anti-Con A or CEA-anti-CEA. CEA can be bound by Con A in solution using the double antibody technique. However, Con A does not inhibit the titration reaction of CEA and anti-CEA by Hansen's Z-gel method. Mannose,

An aptasensor based on electrosynthesized conducting polymers, Cu2O–carbon dots and biosynthesized gold nanoparticles, for monitoring carcinoembryonic antigen
Current work proposes an inimitable composite, with great electrical conductivity and quite enhanced surface area, (including conducting polymers (poly (cathechol)), Cu2O–carbon dots and green synthesized gold nanoparticles) for detecting acute carcinoembryonic antigen. At current work, the electropolymerization was offered instead of enzyme-catalyzed polymerization of poly (catechol). <b...
متن کاملEvaluation of the Relationship between Peroxisome Proliferator Receptors (PPARα, PPARγ, and PPARδ) Expression and Carcinoembryonic Antigen (CEA) in Patients with Colorectal Cancer
Introduction: Studies have shown that an increase in carcinoembryonic antigen (CEA) is associated with the progression of colorectal cancer and is considered a sensitive diagnostic factor for CRC. Moreover, the role of peroxisome proliferators (PPARs) has recently been considered in colorectal cancer. This study aimed to investigate the relationship between the expression level of PPARs and CEA...

متن کاملCarcinoembryonic Antigen Expression and Resistance to Radiation-and 5-Fluorouracil-Induced Apoptosis and Autophagy
Understanding the mechanism of tumor resistance is critical for cancer therapy. In this study, we investigated the effect of carcinoembryonic antigen (CEA) overexpression on UV-and 5-fluorouracil (5-FU)-induced apoptosis and autophagy in colorectal cancer cells. We used histone deacetylase (HDAC) inhibitor, NaB and DNA demethylating agent, 5- azacytidine (5-AZA) to induce CEA expression in HT29...
متن کاملDemonstration of two molecular variants of carcinoembryonic antigen by concanavalin A sepharose affinity chromatography.
The carcinoembryonic antigen (CEA) active glycoproteins from perchloric acid extract of liver-metastasized primary colon tumor have been separated by concanavalin A Sepharose (Con A Sepharose) chromatography. The CEA activities separated by Con A Sepharose chromatography were designated as loosely bound and tightly bound which, respectively, eluted on the Con A Sepharose column between 0.12 and...
