CRH (corticotropin-releasing hormone) is a 41-amino-acid hypothalamic neuropeptide that drives the stress response by stimulating ACTH release from the pituitary and coordinating the hypothalamic-pituitary-adrenal axis in research models. It is supplied as a high-purity white lyophilized powder at >=99% HPLC purity in sealed vials, offering good stability and easy reconstitution. It is widely used in stress biology, anxiety and depression research, neuroendocrinology and receptor-binding assays examining CRH-R1 and CRH-R2 signaling pathways. All batches undergo rigorous quality testing and batch-specific COA documentation can be provided on request. Store unopened vials sealed at 2-8 degree C, away from light and humidity; for longer preservation store at -20 degree C without repeated freeze-thaw cycles. Trial orders and bulk supply are supported, with OEM, private-label and secure neutral packaging available for global delivery. For research use only.
