Description
DSIP (Delta Sleep-Inducing Peptide) — Research-Grade
DSIP is a nonapeptide that has puzzled and fascinated neuroendocrine researchers since it was first isolated from rabbit cerebroventricular blood in 1977. Nine amino acids long, it crosses the blood-brain barrier and shows up in studies of EEG delta-wave activity, circadian rhythm modulation, and hypothalamic-pituitary-adrenal axis response under stress.
Despite the name, what DSIP actually does in vivo remains an active research question. That is exactly why it ends up in so many labs: as a probe for studying sleep architecture in animal models, as a tool for HPA axis perturbation studies, and as a reference compound in opioid receptor interaction research. If you are working in any of those areas, you need a clean source. That is what we are here for.
