Marker of fetal trophoblast cell, identification method, detection kit and use thereof

Abstract

A marker of fetal trophoblast cells, an identification method, a detection kit and the use thereof. The identification method comprises performing dyeing treatment on a sample containing fetal trophoblast cells with a fluorescence-labeled HK2 antibody substance, and then performing fluorescence detection, wherein HK2 positive cells are target cells. The kit comprises a fluorescence-labeled HK2 antibody substance and a cell nucleus dye. The above-mentioned technical solution can sensitively and reliably detect fetal trophoblast cells in the cervical mucus or blood samples of pregnant women in the first trimester, and especially can be used for prenatal diagnosis in early pregnancy.
