一般描述

Potassium bromide is a chaotropic salt, mostly used as an anticonvulsant.

应用

Potassium bromide is used in the preparation of stable Pd nanocubes used in immunolabeling. Potassium bromide is used for the purification of Sarcocystis neurona sporocysts by discontinuous density gradient centrifugation.
可用于除去外周膜蛋白。

生化/生理作用

Potassium bromide is useful in the treatment of refractory seizures or tonic-clonic seizures. It executes a stable excitable membrane by neuron hyperpolarization.

其他说明

In the resolution of flavoproteins into apoproteins and free flavins; Increases yield of extracellular SOD in the extraction from human tissues and cell lines
