  • Antibody for detecting epithelial ovarian cancer marker and method for diagnosing epithelial ovarian cancer
    Patent number: 10247733
    Abstract: It is intended to find a highly specific epithelial ovarian cancer marker and to provide an antibody capable of specifically recognizing and detecting the marker or a fragment of the antibody. The present invention provides an anti-?1,6-N-acetylglucosaminyltransferase 5B antibody for diagnosis of epithelial ovarian cancer, i.e., an antibody for detection of a glycosyltransferase ?1,6-N-acetylglucosaminyltransferase 5B as an epithelial ovarian cancer marker. The antibody recognizes, as an epitope, a part of a polypeptide of the enzyme consisting of the amino acid sequence represented by SEQ ID NO: 1.
    Type: Grant
    Filed: July 26, 2012
    Date of Patent: April 2, 2019
    Assignee: National Institute of Advanced Industrial Science and Technology

  • Antibody for detecting epithelial ovarian cancer marker and method for diagnosing epithelial ovarian cancer
    Patent number: 9816996
    Abstract: The present invention provides an antibody capable of specifically recognizing and detecting the highly specific cancer marker with respect to the epithelial ovarian cancer, or a fragment of the antibody. The present invention provides an anti-?1,3-N-acetylglucosaminyltransferase 3 antibody for diagnosis of epithelial ovarian cancer, i.e., an antibody for detection of a glycosyltransferase ?1,3-N-acetylglucosaminyltransferase 3 as an epithelial ovarian cancer marker. The antibody recognizes, as an epitope, a part of a polypeptide of the enzyme consisting of the amino acid sequence represented by SEQ ID NO: 1.

  • EPITHELIAL OVARIAN CANCER DIFFERENTIATION MARKER
    Publication number: 20150293104
    Abstract: An object of the present invention is to develop and provide an epithelial ovarian cancer diagnosis marker with which epithelial ovarian cancer can be detected inexpensively, conveniently, and low invasively with high accuracy, and a method for determining the presence or absence of epithelial ovarian cancer using the marker. The present invention provides a glycoprotein having a glycan-linked asparagine residue at a particular site of the glycoprotein secreted from an epithelial ovarian cancer cell, or a fragment thereof having the glycan as an epithelial ovarian cancer diagnosis marker. The present invention also provides a method for determining the presence or absence of epithelial ovarian cancer using the glycoprotein.
