【摘要】 目的：在正式进行DIGE实验前，需要进行二维电泳的可行性评价，并测试样品的标记可行性，为荧光差异显示凝胶电泳实验的顺利进行奠定实验基础。方法：选择3只24小时尿草酸排泄量较高的特发性高草酸尿症模型大鼠作为实验组，选择3只24小时尿草酸排泄量在正常范围的SD大鼠作为对照组，切取其肝脏组织后分别提取总蛋白，然后利用双向电泳技术分离蛋白，扫描后获得二维电泳的图谱，并对提取的蛋白样品进行荧光标记实验。结果：总共获得6张稳定清晰的二维电泳图谱和1张SDS-PAGE荧光标记实验电泳图谱。结论：由上述6张二维电泳图谱来看，六个蛋白质样品的蛋白质点的迁移基本稳定正常，且各个蛋白提取液与DIGE荧光染料是兼容的，从而保证后续正式的DIGE实验有较好的重复稳定性和可行性。更多还原

【Abstract】 Objective To evaluate the feasibility of two-dimensional gel electrophoresis liver in ratswith idiopathic hyperoxaluria and labeling before DIGE, and to lay experimentalfoundation for DIGE.Methods 3 male rats with idiopathic hyperoxaluria as study group,3 normal ones ascontrol. The liver of rats with idiopathic hyperoxaluria and the normal liver tissue wereexamined by two-dimensional gel electrophoresis (2-DE) and labeling test.Results Six Satisfying two-dimensional electrophoregram and one SDS-PAGEelectrophoregram were obtained.Conclusions The mobility shift of the protein spots is stable in the six two-dimensionalelectrophoregrams and the protein extract is compatible with DIGE fluorescent dyes.Thestable repeatability and feasibility of DIGE is ensured.更多还原
