Application

Kainic acid (KA) has been used:
  • tostudy mechanisms of excitation-induced apoptosis and epilepsy.
  • to hamper themitochondrial function ()
  • used to induce c-fosexpression in the mice′s brains, specifically targeting the dorsal hippocampus.()

Biochem/physiol Actions

Agonist for kainate class of ionotropic glutamate receptors.
Kainic acid monohydrate disrupts mitochondrial function by inducing the release of lactate dehydrogenase (LDH) and reducing 3-(4,5-dimethylthiazole-2-yl)-2,5-diphenyl tetrazolium bromide (MTT). It also triggers the generation of lipid peroxides, which are key mediators in initiating and regulating inflammation and oxidative stress.
Kainic acid monohydrate is an agonist at the kainate class of ionotropic glutamate receptors, which induces seizures and neurodegeneration in vivo and is used to induce experimental epilepsy in rodents and study the mechanisms of excitation-induced neuronal apoptosis.

General description

Kainic acid monohydrate serves as an agonist for kainate-class ionotropic glutamate receptors, initiating seizures and neurodegeneration in live organisms. It is employed to induce experimental epilepsy in rodents and to explore the mechanisms underlying excitation-induced neuronal apoptosis.

Preparation Note

Dissolve in 1-2 drops of 1N NaOH then bring to volume with water or aqueous buffer. Can be stored 1-2 days refrigerated.
