About Circadian & Neuroendocrine Research

The Circadian & Neuroendocrine Research collection groups peptides studied for their interaction with sleep-regulating and circadian-signaling pathways — including delta-sleep-inducing peptide, VIP, and related neuropeptides. Published research examines their roles in slow-wave sleep architecture, suprachiasmatic-nucleus signaling, HPA-axis modulation, and neuroendocrine feedback loops. Laboratory applications typically include in-vitro receptor-binding assays, gene-expression profiling of clock-related targets (BMAL1, PER, CRY), electrophysiological recordings on hypothalamic slice preparations, and comparative HPLC/MS characterization against published reference peptides. Each vial is supplied as a lyophilized powder manufactured to ≥99% HPLC purity, with a lot-matched third-party Certificate of Analysis available in the online Quality Assurance Center. All items are provided strictly for in-vitro laboratory research by qualified researchers and are not intended for human or veterinary consumption, diagnostic use, or therapeutic application. Storage: keep sealed vials at –20 °C; refrigerate reconstituted samples and protect from direct light.
