离子交换色谱的应用和PCR引物的应用
摘要：
本发明提供一种迅速、简便且高精度的癌预后判定方法。一种肾细胞癌患者的预后判定方法，包括以下工序：(1)将由受检者的肾脏组织制备的基因组DNA用亚硫酸氢盐进行处理的工序；(2)将该被亚硫酸氢盐处理了的DNA通过PCR进行扩增的工序；(3)将得到的PCR扩增产物供给离子交换色谱的工序；(4)获得在该色谱中得到的检测信号的保留时间的工序；(5)工序(4)的结果比成为基准的保留时间早的情况下，将受检者的肾细胞癌判定为预后不良的工序。
摘要（英）：

It is intended to provide a rapid, convenient, and highly accurate method for determining the prognosis of cancer. The present invention provides a method for determining the prognosis of a renal cell carcinoma patient, comprising: (1) treating genomic DNA prepared from a renal tissue of a subject with bisulfite; (2) amplifying the bisulfite-treated DNA by PCR; (3) subjecting the obtained PCR amplification product to ion exchange chromatography; (4) obtaining the retention time of a detection signal obtained by the chromatography; and (5) determining the renal cell carcinoma of the subject as having poor prognosis when the result of the step (4) is shorter than a retention time serving as a reference.
