产品描述: | GFAP 是星形胶质细胞的特异性标志物,作为中间丝蛋白家族成员,其主要功能是维持星形胶质细胞的形态结构稳定,支撑神经元网络架构,同时参与中枢神经系统的损伤修复、营养物质转运及神经递质代谢调节,对维持脑内微环境稳态至关重要。在脑损伤、阿尔茨海默病、帕金森病等神经系统疾病中,星形胶质细胞会发生反应性增生,导致 GFAP 表达显著升高,其水平变化与病变程度、神经损伤修复进程密切相关,是评估神经组织损伤及预后的关键分子标志物。 |

精密度: | ntra-assay Precision (Precision within an assay): CV%<8% |
Three samples of known concentration were tested twenty times on one plate to assess. | |
Inter-assay Precision (Precision between assays): CV%<10% | |
Three samples of known concentration were tested in twenty assays to assess. |
线性度: | To assess the linearity of the assay, samples were spiked with high concentrations of human ACEⅠ in various matrices and diluted with the Sample Diluent to produce samples with values within the dynamicrange of the assay. | ||
