General description

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

Application

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.
May be used for removal of peripheral membrane proteins.

Biochem/physiol Actions

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

Other Notes

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