Abstract: Embodiments relate to serological markers for detecting the colorectal cancer and applications of the serological markers. A phospholipid scramblase1 (PLSCR1), a stomatin-like protein 2 (STOML2) or a transport protein Sec61? (SEC61?) increases expression in the blood at the earlier stage of the colorectal cancer. Detecting the expression of the PLSCR1, STOML2 or SEC61? protein or an induced autoantibody of each protein in a blood sample is used to diagnose the colorectal cancer. Moreover, the serological marker improves the detection efficiency and the sensitivity in detecting the colorectal cancer and is used to predict the prognosis. The serological markers are applied in preparing a detection device or inhibiting the growth of the colorectal cancer cells.

The control unit point and the testing unit point are separated from each other, and a line connecting them is not parallel to the axial direction.

Abstract: The disclosure discloses a method and markers for assessing the risk of having colorectal cancer by a blood sample obtained from an individual. The assessment method includes the steps of: detecting expression levels of a first microRNA and a second microRNA in the blood sample; and assessing the risk of having colorectal cancer for the individual based on a ratio between the expression levels of the first microRNA and the second microRNA. Here, the first microRNA is miR-221, miR-92a, miR-15a, miR-24, miR-18a, miR-191, miR-128, or miR-223, and the second microRNA is miR-10b, miR-100, miR-29a, miR-126, miR-139, miR-31, miR-145, or miR-155. When the first microRNA is miR-128, the second microRNA is miR-10b, miR-100, miR-29a, miR-126, miR-139, miR-31, or miR-145.

Abstract: A method of detecting and measuring levels of a sulfur-containing amino acid in a sample is provided. The method includes combining an enzyme with an aqueous solution possibly comprising a sulfur-containing amino acid. When a sulfur-containing amino acid is present in the solution, it reacts with the enzyme and produces hydrogen sulfide or ammonia. An electrochemical sensor is employed to detect the presence of hydrogen sulfide or ammonia in the solution, and thereby detect the presence of sulfur-containing amino acid. The concentration of sulfur-containing amino acid present in the sample can be quantitatively measured or calculated using this method.

Abstract: A method for detection of mycobacterium tuberculosis antigens in biological fluids provides immunoassay methods, diagnostic kits, and an immunochromatoraphic assay device for detection of Mycobacterium tuberculosis antigens in biological specimens, preferably body fluids and tissues. The preferred body fluids are blood, serum, plasma, urine, pulmonary fluid, sputum, cerebrospinal fluid, and the preferred tissue is the lung biopsy specimen. The immunoassays require two primary antibodies against RD1, RD2, or RD3 of Mycobacterium tuberculosis. At least one of the primary antibodies is attached to a solid carrier. Optional, a second antibody against an animal species producing one of the primary antibodies can be added. Either the other primary antibody or the secondary antibody is labeled with a detection agent, which can be an enzymatic marker, a fluorescent or luminescent agent, a radio active label or a color particle.
