Allopregnanolone ELISA kits are assays designed to detect a neuroactive metabolite of progesterone known as allopregnanolone. Also called brexanolone, it is produced by embryonic and adult central nervous systems and is a positive allosteric modulator of gamma-aminobutyric acid (GABA). It plays a role in variation of mood and anxiety and is used as an antidepressant, anxiolytic, anesthetic, and for the treatment of some neuropsychiatric conditions.
