DSIP (Delta Sleep-Inducing Peptide / Emideltide) – High Purity Premium Peptide API

Product Overview

DSIP, full name Delta Sleep-Inducing Peptide, also named Emideltide, is a natural nine-amino-acid neuropeptide (sequence: Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu).

Used for research on sleep regulation, anti-anxiety, neuroprotection and neuroendocrine mechanism studies.

It is widely applied in laboratory trials for slow-wave deep sleep modulation, stress response adjustment, antioxidant research and HPA axis signaling exploration. Our synthetic DSIP adopts refined peptide synthesis technology, featuring high solubility and stable biological activity after dissolution.

CAS Number: 62568-57-4

Technical Specifications & Quality Attributes

• Purity (HPLC): ≥99.0%
• Identity Confirmation: HPLC + Full MS peptide sequencing, fully consistent with standard molecular weight
• Appearance: Sterile lyophilized white fine powder
• Strict CQA Quality Control:
  Complete detection of residual solvents, heavy metals, bacterial endotoxin, microbial limits, peptide sequence integrity and mass balance;
