Description

Application

Barium chloride dihydrate has been used:

• in patch-clamp electrophysiological studies to block subthreshold-activated potassium channels
• as an inward rectifier potassium (Kir) channel blocker to study the role of the channel by measuring the microglial membrane currents in response to voltage ramp stimuli after ATP injection
• to prepare the stock solution to make artificial cerebrospinal fluid (aCSF)

Biochem/physiol Actions

Barium chloride is a potassium ion channel blocker. It is considered toxic. Barium chloride prevents the D2-like receptor-mediated hyperpolarisation of spinal central pattern generator (CPG) neurons
