DSIP (Delta Sleep-Inducing Peptide) is a nonapeptide first isolated from rabbit cerebral venous blood, since studied across species for its association with delta-wave sleep activity. Research applications include neuroendocrine regulation, stress-response modulation, and circadian research models.

Each vial is lyophilized and shipped with a batch-specific Certificate of Analysis confirming purity via HPLC and mass spectrometry.

Storage: Store lyophilized peptide refrigerated (2–8°C) prior to reconstitution; use bacteriostatic water for reconstitution.
