  • Patent number: 8557602
    Abstract: Disclosed are a method for early, sensitively and reliably detecting and distinguishing intrahepatic cholangiocarcinoma in a malignant tumor occurring primarily in the liver in a simple way, and a kit thereof. In the method, a glycan biomarker consisting of a lectin WFA (Wisteria floribunda Agglutinin)-binding glycoprotein derived from intrahepatic cholangiocarcinoma is used as a cancer marker to detect intrahepatic cholangiocarcinoma by detecting the cancer marker in a test specimen. The method for detecting intrahepatic cholangiocarcinoma can clearly differentiate intrahepatic cholangiocarcinoma from hepatocellular carcinoma and enables early detection and determination with a performance clinically acceptable in terms of applicability, sensitivity and precision.

  • Patent number: 8551713
    Abstract: The present invention relates to a series of markers and a method of determining cause of death post-mortem by quantifying thymus integrity. An examination of thymuses from human infants suffering mortal head trauma revealed a disruption of the cortical-medullary organization of the thymus, particularly involving dissolution of the cortical-medullary border. A similar result was obtained for related mouse and rat models. The human thymuses from head trauma cases also displayed a higher percentage of Ki67-positive thymocytes.

  • Patent number: 8535894
    Abstract: Provided are labeling reagents and methods for labeling primary antibodies and for detecting a target in a sample using an immuno-labeled complex that comprises a target-binding antibody and one or more labeling reagents. The labeling reagents comprise monovalent antibody fragments or non-antibody monomeric proteins whereby the labeling proteins have affinity for a specific region of the target-binding antibody and are covalently attached to a label. Discrete subsets of labeling reagent and immune-labeled complexes are provided that facilitate the simultaneous detection of multiple targets in a sample-complexes are distinguished by i) a ratio of label to labeling reagent, or ii) a physical property of said label, or iii) a ratio of labeling reagent to said target-binding antibody, or iv) by said target-binding antibody. This is particularly useful for fluorophore labels that can be attached to labeling reagents and subsequently immuno-labeled complexes in ratios for the detection of multiple targets.
