Orexin A (Hypocretin-1) is a naturally occurring 33 amino acid neuropeptide produced exclusively by neurons in the lateral hypothalamus and perifornical area. As one of two orexin peptides (alongside Orexin B) cleaved from the prepro-orexin precursor protein, Orexin A acts as an agonist at both OX₁R and OX₂R orexin receptors with approximately equal affinity. It is used as a research tool in neuroscience investigations of arousal pathway regulation, circadian rhythm biology, appetite signalling, and orexin receptor pharmacology in vitro.
Orexin A is manufactured in a cGMP compliant, ISO9001 certified laboratory to a guaranteed purity of ≥98%. Every batch is independently tested using HPLC and MS-UPLC analysis before dispatch.
Vials are vacuum sealed and stored in a temperature-controlled, monitored cold storage system to preserve purity throughout the supply chain. Certificates of Analysis are available on request.
Sold strictly for in vitro research purposes only. Not for human consumption.
