What is DSIP?

DSIP (delta sleep-inducing peptide) is a peptide of nine amino acids. Swiss researchers Schoenenberger and Monnier isolated it from the cerebral venous blood of rabbits in deep sleep.

Despite decades of research, no specific receptor for DSIP is known to date. This open question is exactly what makes the peptide interesting for basic research.

DSIP in research

DSIP was originally studied because of a suspected influence on delta sleep. Later studies showed inconsistent results, so its role in sleep regulation is still being debated.

Other preclinical work deals with stress responses, hormone balance and neuroendocrine signalling pathways.

Technical data

The certificate of analysis for each batch is authoritative.

What you receive

You receive a sealed glass vial containing 10 mg DSIP as a lyophilised powder. The label states the product name, content and batch number, so every vial can be matched clearly to the corresponding test report.

Orders are shipped in neutral, padded packaging. No instructions for human use are included, because the product is intended exclusively for laboratory research.

Quality: what matters when you buy DSIP

If you want to buy DSIP, look above all for traceable batch documentation. We publish available third-party test reports in our certificate of analysis library. There you can see which tests – such as HPLC for purity or mass spectrometry for identity – exist for the specific batch.

General substance data on DSIP is also available in the free PubChem database of the US National Center for Biotechnology Information.

Laboratory storage

Lyophilised peptides are considerably more stable in dry form than in solution. For laboratory storage, −20 °C, dry and protected from light, is recommended. Room temperature for short periods, for example during shipping, is not critical.

Repeated freeze-thaw cycles should be avoided. Further handling follows your laboratory's requirements and standard operating procedures (SOPs).
