Beschreibung

Allgemeine Beschreibung

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

Anwendung

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.

Kann zur Entfernung peripherer Membranproteine eingesetzt werden.

Biochem./physiol. Wirkung

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