What is Dsip ?
DSIP, short for δ-Sleep-Inducing Peptide, also known as emitidine, is a well-studied endogenous nonapeptide with significant research value in sleep physiology, neuroprotection, and stress response regulation. This product is a research-grade lyophilized peptide powder provided by Novio, manufactured strictly according to laboratory research standards and verified by high-performance liquid chromatography (HPLC) with a purity ≥99%. Each batch comes with a complete Certificate of Analysis (COA) to meet the stringent quality requirements of academic laboratories, research institutions, and biochemical product distributors worldwide. Unlike many synthetic peptides, DSIP is a naturally occurring peptide, first isolated from rabbit cerebral venous blood in 1974, making it a reliable and safe tool for exploring sleep regulation and neurobiological mechanisms in preclinical research models.
