METHOD FOR DETECTION OF CANCER

摘要

Disclosed is a method for detecting cancer by employing the expression of a specific polypeptide as an indicator. The polypeptide is isolated as a polypeptide capable of binding to an antibody that occurs in a serum collected from a cancer-bearing living body by the SEREX method using a cDNA library derived from a canine testis and a serum collected from a cancer-bearing dog. The polypeptide can react with an antibody occurring specifically in a serum from a cancer patient. Therefore, the occurrence of cancer in a living body can be detected by measuring the antibody in a sample. The occurrence of cancer in a living body can be also detected by measuring an antigenic protein for the antibody or mRNA encoding the antigenic protein.
