DSIP Delta Sleep-Inducing Peptide CAS 62568-57-4

 Basic Product Information

DSIP, full name Delta Sleep-Inducing Peptide, also named Eptadepsipeptide, is a synthetic nine-amino-acid peptide with neural regulation activity. Its CAS registry number is 62568-57-4, molecular formula C₃₅H₄₄N₁₀O₁₃, molecular weight 848.95. This high-purity lab-use biochemistry raw material is produced via solid-phase peptide synthesis technology and refined by high-performance liquid chromatography (HPLC). The finished product keeps stable purity ≥98%, fully matching the testing standards of life science labs, neural cell research, biochemistry material development, in-vitro cell culture and other academic research

This peptide was first separated from mammal thalamic tissue by global research teams, serving as an endogenous active peptide that adjusts resting cycle signals. It balances deep resting cycle states by adjusting the secretion of central nerve signal factors. Different from traditional synthetic sedative chemical materials, it only targets resting signal pathways without long-term neural function dependency risks, making it a core lab raw material for current neural cell research, resting cycle study and anti-oxidation aging mechanism exploration.

Core Product Advantages 

This product adopts Fmoc solid-phase synthesis, with full reaction under water-free and oxygen-sealed environment. Crude material is purified by reversed-phase HPLC gradient elution, followed by repeated desalting and freeze-drying treatment. Final HPLC purity stays ≥98.0%, single unknown impurity ≤0.5%, total impurity controlled within 2%. All quality control indicators including heavy metal content, moisture and burning residue follow national polypeptide reagent industry standards.

Finished products are stored in dual normal-temperature and low-temperature sample retention environments for 12 months, and customers can apply for re-inspection at any time. Thousands of batch supply records in the past 3 years show no difference in purity, activity and physical-chemical features between batches, which ensures stable repeatable test data and avoids trial failure caused by raw material quality fluctuation.

Superior stable product quality with GMP standardized production, triple strict batch testing and ≥98% high purity, low impurity without experimental interference; thoughtful professional after-sales service with patient communication attitude and free technical consultation & full test document supply; cost-effective price with flexible customized packaging and stable bulk supply to reduce your research cost.
