增殖细胞核抗原（ＰＣＮＡ）是ＤＮＡ多聚酶δ的辅助蛋白，存在于细胞周期，与ＤＮＡ合成和细胞周期有密切关系，是判定肿瘤增殖分化程度的良好指标。本课题应用抗ＰＣＮＡ抗体对肝癌组织进行免疫组化染色，检测抗体的表达，分析其意义，报道如下。１材料与方法材料来源：...
Proliferating cell nuclear antigen (PCNA) is an accessory protein of DNA polymerase δ. It exists in the cell cycle and is closely related to DNA synthesis and cell cycle. It is a good indicator of tumor proliferation and differentiation. In this study, anti-PCNA antibody was used to immunohistochemically stain hepatocarcinoma tissue, detect antibody expression, and analyze its significance. The report is as follows. 1 Materials and Methods Materials Source:...
