[Purpose] I found haptoglobin who received sugar chain modification cancer-specific from malignant prostate cancer patients serum. The antibody was produced to antigen glycosylated peptide from a cancer patient serum-derived haptoglobin. I aimed at the early diagnosis of prostate cancer. [Result] Antibody produced was possible to distinguish healthy control and malignant prostate cancer patients. To also distinguish between malignant prostate cancer and benign disease patients was also possible. The prototype that can be measured by ELISA was able to sufficient sensitivity is obtained.It was detectable the number ng / ml sugar chain haptoglobin in serum. I was able to produce ELISA to make up for the shortcomings of PSA levels. Furthermore, we want to raise the accuracy of the early diagnosis method by increase the number of samples.
