近年来 ,我们将银染法应用于端粒酶活性的检测过程中 ,认为有助于提高胃癌组织端粒酶活性检测的敏感性 ,现报告如下。资料与方法 :32例胃癌组织及 32例癌旁组织均取自外科手术 ,病理检查均为鳞状细胞癌。PCR仪为美国 PE公司产品 ,端粒酶活性检测试剂盒购自山东医科大学遗传教研 In recent years, we have applied the silver staining method to the detection of telomerase activity, and we believe that it is helpful to improve the sensitivity of detection of telomerase activity in gastric cancer tissues. The report is as follows. Materials and Methods: 32 cases of gastric cancer tissues and 32 cases of adjacent tissues were taken from surgical operation. All pathological examinations were squamous cell carcinoma. The PCR instrument was produced by the American PE company. The telomerase activity test kit was purchased from Shandong Medical University.
