Scientific context

DSIP owes its name to the circumstances of its discovery: it was isolated from the cerebral venous blood of animals in the phase ofslow-wave sleepand its administration was changing the activitydeltato the electroencephalogram. This origin explains its designation as "delta sleep-inducing peptide".

Half a century later, the DSIP remains aopen subject of studyThe published works focus on sleep architecture, but also on the stress response, neuroendocrine modulation, and thermoregulation. NoneNo specific receptor has been identified to date.and its mechanism of action remains debated — which makes it precisely a subject of basic research rather than a characterized compound.

Laboratory reconstruction

The freeze-dried powder is reconstituted withbacteriostatic waterAdd slowly against the side of the bottle without vigorous shaking. After reconstitution, the solution should be stored in a refrigerator, protected from light. Handling should only be carried out by qualified laboratory personnel using appropriate sterile equipment.
