Abstract
A method of collecting and detecting a tumor cell contained in a sample in distinction from a contaminant cell is provided. The tumor cell contained in the sample are collected and detected in distinction from the contaminant cell by detecting any of the following polypeptides or a gene encoding the polypeptide present in the sample: (i) a polypeptide containing at least the amino acid sequence of any of six sequences such as TM4SF1 (GenBank No. NP_055035.1) and TNFRSF12A (GenBank No. NP_057723.1); (ii) a polypeptide containing at least an amino acid sequence having a homology of not less than 70% to the amino acid sequence described above; and (iii) a polypeptide containing at least a splicing variant of the amino acid sequence (the amino acid sequence of (i) or (ii) described above).
