【Product Overview】 We are a specialized global supplier of DSIP (Delta Sleep-Inducing Peptide), a naturally occurring nonapeptide originally isolated from the cerebral venous blood of rabbits. Known for its unique ability to cross the blood-brain barrier (BBB), DSIP is a critical reagent for neuroscience research focusing on sleep regulation, circadian rhythms, and stress recovery. We provide high-purity, synthetic DSIP to research institutions and pharmaceutical developers investigating neuromodulation and endocrine response.

【Key Advantages】

Sleep & Circadian Research: DSIP is the premier peptide for studying "Delta Wave" (slow-wave) sleep induction and the normalization of sleep cycles, making it essential for insomnia and narcolepsy models.

Stress Protection: Beyond sleep, our DSIP is widely studied for its potent antioxidant properties and its ability to mitigate the physiological effects of acute stress (corticosterone reduction), appealing to longevity and anti-aging researchers.

High Purity Synthesis: We guarantee ≥98.0% purity (HPLC). Our synthesis platform ensures the correct amino acid sequence without truncation, providing a reliable baseline for sensitive neurological assays.

High Solubility: Our lyophilized powder is highly soluble in water, facilitating easy preparation for in vitro and in vivo administration.
