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 |
