This disclosure relates to a circulating tumour
cell typing and identification kit, comprising a capture probe, an amplification probe, and a labeled probe for each
marker gene mRNA, wherein the
marker gene mRNA comprises the following two types: at least two epithelial
cell marker gene mRNAs selected from the group consisting of EPCAM, E-
cadherin, CEA, KRT5, KRT7, KRT17, and KRT20 mRNAs; and, at least two mesenchymal
cell marker
gene mRNAs selected from the group consisting of
VIMENTIN, N-
cadherin, TWIST1, AKT2, ZEB2, ZEB1, FOXC1, FOXC2, SNAI1 and SNAI2 mRNAs. This disclosure prevents false-positive results caused by, for example, possible presence of a number of non-neoplastic epithelial cells in
peripheral blood, introduction of normal epithelial cells during
blood sampling, and the like. Accordingly, it may be assured that cells detected with epithelial
cell marker genes and / or mesenchymal
cell marker genes are indeed circulating tumour cells, further improving accuracy and reliability of the detection results.
