Biochem/physiol Actions

尼日利亚菌素是一种聚醚离子载体,可催化碱金属(K+)与 H+(反位)的电子中性交换。
尼日利亚菌素是一种聚醚离子载体,可催化碱金属(K+)与 H+(反位)的电子中性交换。 尼日利亚菌素跨膜转运单价阳离子具有以下特异性:K+ >Rb+ >Cs+ >>Na+,从而破坏膜电位并刺激线粒体中的 ATPase 活性。
尼日利亚菌素通过促进离子跨膜扩散来杀死细菌。
低浓度(0.5 μM)的尼日利亚菌素会迅速降低 pHi,导致在大脑微血管内皮细胞中刺激 PG 产生 1.5 到 2 倍,并阻止 Erlich 腹水癌细胞中 DNA 的合成。 在脊髓灰质炎病毒进入 Hela 细胞后,用尼日利亚菌素处理可防止脊髓灰质炎病毒对宿主蛋白合成的抑制。 尼日利亚菌素还广泛用于研究可变系统中膜电位变化的后果。

Preparation Note

以 6.7 mM 的浓度提供尼日利亚菌素钠盐制备的溶液。 可用所需溶剂将该溶液进一步稀释至工作浓度(0.5-10 μM)。
该产品为5mg /mL溶液,DMSO和乙醇按1:1混合配制。
该产品可在2-8°C下保存,建议每4年重新检测一次。该溶液在冷藏条件下相当稳定,无需冷冻。

Non-canonical inflammasome activation that recognizes intracellular lipopolysaccharide (LPS) causes pyroptosis, the inflammatory death of innate immune cells. The role of pyroptosis in innate immune cells is to rapidly eliminate pathogen-infected cells and limit the replication niche in the host body.
