Patent ID: 11255859

Abstract:
The present application relates to use of hexokinase-2 and a kit for detecting rare tumor cells in body fluid sample. The present application, based on a principle of abnormal tumor cell energy metabolism, conducts a vitro detection by using a glycolysis marker hexokinase-2 (HK2) as a marker, and assists localization and selection of the rare tumor cells by an addressable microporous array chip or a glass sheet, so as to implement a detection on rare tumor cells having high glycolysis activity in a cancer patient's body fluid sample. The detection method of present application allows to detect rare tumor cells having high glycolysis activity in the human body fluid sample, especially detect circulating tumor cells of an interstitial origin tumor and the circulating tumor cells having epithelial-interstitial transformation in epithelial origin tumors, thereby covering the shortage of traditional detection against the circulating tumor cells based on an epithelial marker, and providing a technical basis for better application of cancer liquid biopsy in clinic.
