DSIP is a nonapeptide (Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu) first isolated in 1977 from the cerebral venous blood of rabbits. It has since been detected in the brain, peripheral tissues and body fluids of several species, yet no dedicated precursor gene or receptor has been identified, which keeps it an open question in neuropeptide biology. Laboratories use DSIP as a reference peptide in neuroendocrine and neuropeptide-signaling research.

Is this product for human or veterinary use?
No. It is sold strictly for in vitro and laboratory research. Not for human or animal use.
All compounds referenced are supplied for laboratory and research applications only and are not for human consumption.
DSIP has been studied for almost five decades, and the literature is notable for how much remains unresolved. An early comprehensive review catalogued its distribution across tissues, its structural features and the broad range of physiological systems in which it had been examined, from neuroendocrine regulation to stress-response models.1
A later critical review revisited that work and concluded that, despite a large body of experimental data, the peptide’s natural origin, gene and receptor were still unknown. That gap is the main reason DSIP remains of interest: it is a short, well-defined sequence whose biological role has not been pinned down.2
