Specific Carcinoembryonic Antigens of the Human Digestive System
A wide variety of human adult and fetal tissues were studied by immune-diffusion techniques in agar gel to determine whether they contained the tumor-specific antigen(s) previously found in coionic cancers. In the adult tissues it was demonstrated that identical antigens were present in all tested specimens of malignant tumors of the entodermally derived epithelium of the gastrointestinal tract...
متن کاملPhysicochemical Studies of the Carcinoembryonic Antigens of the Human Digestive System
A procedure has been described for the purification of the carcinoembryonic antigens (CEA) of the human digestive system. Tumor tissue extraction in 0.6 M perchloric acid followed by paper block electrophoresis and column chromatography on Sephadex G-200 resulted in highly purified CEA preparations as determined by both immunological and physicochemical criteria. The properties and composition ...
متن کاملThe radioimmunoassay of circulating carcinoembryonic antigen of the human digestive system.
A radioimmunoassay has been developed for determining the serum levels of carcinoembryonic antigen of the human digestive system in patients with cancer of the colon and rectum. The assay is simple to perform and has a high degree of reproducibility and specificity. The test detects a concentration of 2.5 ng of carcinoembryonic antigen per ml of serum and this has provided the first demonstrati...

Sturgeon is one of the most important species of the Caspian Sea aquatics. Unfortunately, this species faces the threat of extinction today. This makes specific studies on any type of sturgeons more important than before. Studies like histological studies, radiology, and sonography, all require a complete understanding of the anatomy of this fish. Since pilot studies showed some misconceptions ...
