Overview
Delta-Sleep-Inducing Peptide (DSIP) is a 9-residue endogenous neuropeptide originally isolated from cerebral venous blood of sleeping rabbits. Despite the name, its primary research interest extends beyond sleep architecture into stress-response, opioid-receptor modulation, and circadian-axis pharmacology.
Each vial is lyophilized from acetate buffer, sealed under nitrogen, and shipped ~4 days from our lab.
Sold for laboratory research only. This material is not a drug, food, or cosmetic and is not intended for diagnostic, therapeutic, or recreational use.

Allow vial to reach room temperature before opening (≥ 20 minutes). Reconstitute with 1.0-2.5 mL of sterile bacteriostatic water (0.9% benzyl alcohol). Inject solvent slowly down the inner wall of the vial; do not direct stream onto the lyophilized cake.
Swirl gently for 30 seconds. Do not vortex. Allow to dissolve for 5 minutes; clarity should be complete with no visible particulates.
Storage after reconstitution
Reconstituted solution is stable for 28 days at 2-8 °C in original vial. For longer storage, aliquot into low-binding tubes and hold at −80 °C; avoid repeated freeze-thaw cycles. Discard if turbidity, color change, or particulate matter is observed.
