生化/生理作用

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。

準備報告

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)。
This product is a 5 mg/mL solution prepared in a 1:1 mixture of DMSO and Ethanol.

儲存和穩定性

Questions

  1. How stable is the antibiotic in solution, how long can I store it for? Can I freeze a few aliquots in -80 deg C, or will it cause the chemical to denature?

    1 answer
    1. This product is a 5 mg/mL solution prepared in a 1:1 mixture of DMSO and Ethanol. The product is stored at 2-8°C and is released with a 4 years suggested retest schedule. The solution is quite stable refrigerated and freezing is not necessary. However, the pure powder product (N7143) is stable at -20°C for at least 3 months when dissolved in DMSO or Ethanol. Storage at less than -20°C has not been evaluated. Please see the link below for a sample Certificate of Analysis which includes the recommended retest date:
