目前,经过GS试剂处理制作的蜡块在放置较长时间后对组织抗原的保存效果的报道却较少。因此,我们通过免疫组化染色和分子学检测,对60例标本组织中21种抗体进行了回顾性检测,测试经GS试剂处理制作的蜡块经过2年放置后组织抗原的保存情况。1材料与方法1.1材料选取河南省人民医院病理科2011-07—12间手术切除标本60例,其中乳腺癌、结肠癌、卵巢癌、宫颈癌、间 At present, there are few reports on the preservation effect of tissue antigens after being placed in the GS reagent for a long time. Therefore, by immunohistochemical staining and molecular detection, 21 kinds of antibodies in 60 specimens were retrospectively examined to test the preservation of tissue antigens after 2-year placement of wax blocks prepared by GS reagent treatment. 1 Materials and Methods 1.1 Materials Selection Henan Provincial People’s Hospital Department of Pathology 2011-07-12 60 cases of surgical resection specimens, including breast cancer, colon cancer, ovarian cancer, cervical cancer, between
