What is DSIP?
DSIP, in full delta sleep-inducing peptide (INN: emideltide), is a nonapeptide with the sequence Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu (WAGGDASGE). The molecular formula is C35H48N10O15, the molecular mass 848,8 g/mol and the CAS number 62568-57-4. The peptide was described in the 1970s following isolation from the blood of rabbits during sleep; the name refers to the delta waves in the EEG that were observed at the time.
What is the research about?
The literature on DSIP is largely older work. A review in Neuroscience & Biobehavioral Reviews (1984) describes research in animal models and in humans on sleep and on diverse neurological and physiological processes; European Journal of Anaesthesiology published an overview in 2001. What stands out when reading: the mechanism of action remains unelucidated after decades of research, and the findings regarding sleep are not unequivocal. That is more relevant than the peptide's name might suggest. DSIP is not registered as a medicine anywhere.

Stap 1
Purity by HPLC
Liquid chromatography separates the sample; purity is the proportion represented by the main peak.
Stap 2
Identity by FTIR
FTIR compares the sample’s infrared spectrum with a reference spectrum to confirm identity.
Stap 3
Content by quantitative testing
A separate measurement determines how much substance is in the vial, where included in the report.

What does the name delta sleep-inducing peptide mean?
The name originates from the 1970s, when researchers observed increased delta waves on the EEG in rabbits following exposure to the peptide. Later studies did not provide an unambiguous picture, and the mechanism has still not been elucidated.
How do I store DSIP?
Unopened and lyophilized at −20 °C, dark and dry. After reconstitution at 2–8 °C and process within the timeframe of your protocol, typically 28–30 days.
How do I reconstitute DSIP?
With bacteriostatic water: let it run down the glass wall and gently swirl, do not shake. The peptide calculator converts vial content and volume into a concentration.
Where do I find the lab report?
In the lab report block on this page. There you see which report belongs to the selected variant, what strength it is, and how you verify it yourself with the lab.
What is the difference between DSIP and Selank?
They are different peptides: DSIP is a nonapeptide (9 amino acids), Selank a synthetic heptapeptide derived from tuftsin. Both feature in neurobiological research, with their own literature.
What is the shelf life of DSIP?
As a dry powder at −20 °C, long; the exact expiration date is stated on the label. Reconstituted, shorter: keep refrigerated and process within your protocol timeframe.
How is it shipped and does it need to be refrigerated?
The lyophilized powder is shipped dry from the Netherlands, neutrally packaged with sender: within the Netherlands usually the next business day, within the EU 1–4 business days. Upon receipt, place the vial directly into the freezer (−20 °C).
What is in the package?
One vial of lyophilized powder, labeled as research use only. Bacteriostatic water, syringes, and alcohol swabs are not included as standard and can be ordered on this page.
How do I place an order?
Place products in your shopping cart and complete the order at checkout. There you enter your details, choose a payment method, and confirm the three mandatory declarations.
