Compound
DSIP
DSIP is supplied by PX1 Research as a lyophilized research-grade nonapeptide isolated from rabbit cerebral venous blood at ≥99% HPLC purity, for laboratory use only.
Overview
DSIP is supplied by PX1 Research as a research-grade lyophilized material classified as a nonapeptide isolated from rabbit cerebral venous blood. It is characterized for laboratory investigation in sleep-architecture research, and every vial is traceable to a lot record with analytical data behind it.

Handling and reconstitution
Sealed lyophilized vials are stable in ambient transit and should be held cool, dry and dark on arrival; −20 °C is preferred for long-term storage. A typical working preparation for this vial size is 5 mg + 2 mL = 2.5 mg/mL. Direct the diluent stream down the inside wall of the vial rather than onto the cake, swirl gently rather than shaking, label the vial with concentration and date, and hold reconstituted material at 2–8 °C. Use the peptide calculator to convert milligrams to U-100 units.
