Methods］ A total RNA from 10 cases withovarian papillary serous cystadenocarcinoma and normal ovarian tissues were extracted by a single step method of gene chip. The cDNA retro?鄄transcribed from equal quantity mRNA derived from 10 cases with ovarian papillary serous cystadenocarcinoma and normal ovarian tissues. The cDNA strand was labeled with fluorescent Cy5 and Cy3(normal ovarian epithelial cells) as probes.

方法］ 采用基因芯片技术，按一步法分别抽提10例卵巢浆液性乳头状囊腺癌患者的癌组织和正常卵巢组织的总RNA并纯化mRNA；逆转录合成以Cy5荧光标记卵巢癌细胞和Cy3荧光标记正常卵巢上皮细胞的cDNA作为探针，在含有8 464点人类体细胞基因模板的表达谱cDNA芯片上进行杂交。

Methods The cDNA retro-transcribed from equal quantity total RNA derived from rectal carcinoma or normal rectal mucosa were labeled with Cy5 or Cy3 fluorescence as probes respectively. The mixed probes were hybridized with the BioStar 4096 cDNA microarray.

分别抽提直肠腺癌和正常直肠粘膜的总RNA；通过逆转录方法将Cy3和Cy5两种荧光分别标记到两组cDNA上，制成探针；利用这种cDNA探针与含有4096条人类基因PCR产物的表达谱芯片进行杂交，扫描芯片荧光信号图像，计算机分析后比较两种组织中差异表达的基因。
