  • METHOD AND REAGENT FOR DETECTING OVARIAN CLEAR CELL ADENOCARCINOMA
    Publication number: 20170322218
    Abstract: The present invention aims to provide a method for detecting, with high sensitivity and specificity, ovarian clear cell adenocarcinoma, which is highly malignant, among benign and malignant ovarian tumors having various tissue types, and a reagent that can be used for the method. The present invention provides NT-TFPI2, which is a novel processed tissue factor pathway inhibitor 2 polypeptide, as a new detection marker for ovarian clear cell adenocarcinoma. The detection of ovarian clear cell adenocarcinoma is carried out by measuring the amount of NT-TFPI2, or the total amount of NT-TFPI2 and intact TFPI2. The reagent for detecting ovarian clear cell adenocarcinoma contains an antibody that specifically recognizes NT-TFPI2 and intact TFPI2.
