| 摘要 |
The present invention relates to a method for diagnosing colon cancer by detecting a colon cancer specific antigen, defensin alpha 6 from the blood of patient and a diagnostic kit for colon cancer comprising anti-defensin alpha 6 antibody, The diagnostic kit for colon cancer of present invention comprises, a solid support such as 96-well plate for ELISA, nitrocellulose membrane, polyvinylidene fluoride membrane, microplate, glass substrate, polystyrene substrate, silicone substrate or metalplate, on which anti-defensin alpha 6 antibody is immobilized; and, a means for detecting colon cancer specific antigen such as a primary antibody which specifically binds with an antigen conjugated with an antibody on a solid substrate and a secondary antibody-signal complex which specifically binds with the primary antibody. The diagnostic kit of the invention can diagnose colon cancer with the minute amount of patients' blood, which makes possible the easy and simple diagnosis of colon cancer.
