Biosensor Technology Reveals the Disruption of the Endothelial Barrier Function and the Subsequent Death of Blood Brain Barrier Endothelial Cells to Sodium Azide and Its Gaseous Products.
本文报道利用电细胞基底阻抗传感(ECIS)生物传感器技术,实时、无标记地监测人血脑屏障(BBB)内皮细胞屏障完整性,揭示叠氮化钠(sodium azide)及其挥发性气体产物对脑微血管内皮细胞的毒性。叠氮化钠常作为抗体等生物试剂防腐剂,在低毫摩尔浓度下具有急性细胞毒性。研究最初在含叠氮化钠抗体实验中观察到屏障完整性延迟丧失,而无叠氮...
