Description

General description

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

Application

May be used for removal of peripheral membrane proteins.

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.

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.

Features and Benefits
