Note Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20°C. Generally, these will be useable for up to one month. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.

Product Description

Pregnenolone is an endogenous neurosteroid that is involved in the steroidogenesis of progesterone, glucocorticoids, mineralocorticoids, androgens, and estrogens, making it a prohormone. It has been observed to inhibit GABA-gated chloride currents by enhancing receptor desensitization. Pregnenolone is an inhibitor of GABA Receptor and an activator of PXR.
An prohormone neurosteroid also a precursor to gonadal steroid hormones and the adrenal corticosteroids.
