Research Context
DSIP takes its name from the experimental context in which it was first identified rather than from any established mechanism; the literature notes its mechanism remains incompletely characterised. Ascend Research supplies DSIP strictly as a laboratory reference material; no representation is made regarding any physiological outcome, and it is not supplied for use in humans or animals.
Handling and Reconstitution
Allow the vial to reach room temperature before opening. Reconstitute with sterile water and swirl gently. Store the lyophilised powder dry at 2–8°C, refrigerate reconstituted material and use within 30 days. Avoid repeated freeze–thaw cycles.
What's Included
- One lyophilised vial (5mg or 15mg, as selected)
- Protective packaging
