설명

일반 설명

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

애플리케이션

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.

생화학적/생리학적 작용

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