DSIP

Also known as Delta sleep-inducing peptide

DSIP, or delta sleep-inducing peptide, is a nonapeptide: a chain of nine amino acids. It was first isolated in the 1970s by Swiss researchers studying sleep in rabbits, which is where its name comes from.

Structure and form

Sequence	Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu
Molecular formula	C35H48N10O15
Molecular weight	848.8 g/mol
Form	Lyophilised powder
Storage	−20 °C, protect from light

Research background

DSIP has been studied in animal models of sleep and of stress responses.

Its natural role and the receptor it acts through are still not clearly established, and published results have been mixed.

It is not an approved medicine in the UK or elsewhere.

Storage and handling

Supplied as a lyophilised (freeze-dried) powder in a sealed 4 ml vial. Keep it sealed until use. Storage: −20 °C, protect from light. Once reconstituted, solutions are usually kept refrigerated at 2–8 °C and used promptly. Follow your laboratory's own protocols and safety data.

Is DSIP approved for human use?

No. DSIP is sold by vialinepeptides strictly for in-vitro laboratory research. It is not a medicine, food or cosmetic and is not for human or veterinary use. Nothing on this page is medical advice.
