Delta Sleep Inducing Peptide (DSIP), an endogenous neuropeptide composed of nine amino acids, plays a crucial role in sleep regulation. It rapidly induces slow-wave sleep (non-rapid eye movement sleep) in animals by enhancing γ-aminobutyric acid (GABA) activity and inhibiting N-methyl-D-aspartate (NMDA) receptors. Subsequent studies have revealed that DSIP not only promotes slow-wave sleep but also regulates rapid eye movement sleep. Additionally, DSIP exhibits antioxidant, anti-anxiety, and neuroprotective properties, and is involved in physiological processes such as endocrine regulation, stress limitation, thermoregulation, and cardiovascular function stability. In disease research, DSIP has shown anticancer potential (e.g., reduced tumor incidence in mice) and antidepressant effects, though conflicting results exist regarding its level changes in depressed patients. The peptide is easily degraded in vivo (with a half-life of approximately 15 minutes), likely maintaining stability through binding to carrier proteins or as part of precursor molecules.
DSIP is mainly prepared by chemical synthesis and should be stored in the form of freeze-dried powder at-20℃ to avoid repeated freeze-thaw.

Q7:  How to preserve peptides after receiving them?
A:Peptides in the form of lyophilized powder can be transported at room temperature by vacuum packaging, while polypeptides in the dissolved state need to be refrigerated at 2 ° C - 8 ° C. For long-term storage, peptides should be stored in the form of lyophilized powder store at -20 ° C or -80 ° C in a sealed container with desiccant, which can avoid the degradation of peptides to the greatest extent.
