DSIP:
A Research
Overview
DSIP (delta sleep-inducing peptide) is a naturally occurring peptide of nine amino acids, first isolated from cerebral venous blood in 1977. Its mechanism remains incompletely characterised, and it appears in neurological research on endogenous signalling peptides. Supplied for research use only.
What DSIP is
DSIP, or delta sleep-inducing peptide, is a naturally occurring peptide of nine amino acids (sequence WAGGDASGE). It is a nonapeptide — the term simply denotes its nine-residue length. Unlike several other compounds in this library, it is an endogenous molecule rather than a synthetic analogue.
It is supplied as a lyophilised powder for laboratory research.
Background and discovery
DSIP was first isolated in 1977 from the cerebral venous blood of rabbits during slow-wave (delta-wave) sleep — the circumstance that gives the peptide its name. That origin has framed the research literature around it ever since.
It is worth being candid about the state of that literature: the mechanism of DSIP remains incompletely characterised, and it is studied as an endogenous peptide of uncertain physiological role. It holds no marketing authorisation and is not supplied for human use. No claim is made as to any effect in people.
Areas of research interest
Research involving DSIP sits within neuropeptide science:
- Neuropeptide signalling — the study of endogenous signalling peptides in the nervous system.
- Sleep-related neurochemistry — reflecting the circumstances of its discovery, studied in model systems.
- Endogenous peptide characterisation — work aimed at clarifying its still-uncertain role.
These are areas of laboratory investigation, not effects established in humans.
Research context
DSIP is studied as one of many endogenous neuropeptides whose signalling roles are still being mapped. The product listing gives the specification and batch certificate.
Frequently Asked Questions
DSIP (delta sleep-inducing peptide) is a naturally occurring peptide of nine amino acids (sequence WAGGDASGE), first isolated from cerebral venous blood in 1977. It is supplied as a lyophilised powder for laboratory research use only.
It was first isolated in 1977 from the cerebral venous blood of rabbits during slow-wave (delta-wave) sleep, which is the circumstance the name refers to. The name reflects its origin, not an established effect.
Not fully. The mechanism of DSIP remains incompletely characterised in the published literature, and it is studied as an endogenous peptide of uncertain physiological role. It is supplied for laboratory research use only.
