Neuropeptide Research

Neuropeptide research examines short peptide sequences that act as signaling molecules within the central and peripheral nervous systems, typically at concentrations far below those of classical neurotransmitters. Compounds in this category include Selank, a synthetic analog of the endogenous immunomodulatory tetrapeptide tuftsin, studied in behavioral and neuroimmune models; and DSIP (delta sleep-inducing peptide), a nonapeptide first isolated from rabbit cerebral venous blood and characterized in neuroendocrine research literature. Peptides in this group are supplied lyophilized. Because short neuropeptide sequences can be sensitive to repeated freeze-thaw cycling and to light exposure, handling and storage guidance is documented on each product page. Every lot ships with a batch-specific certificate of analysis confirming identity by mass spectrometry and purity by HPLC-UV. All products in this category are supplied strictly for laboratory research use. They are not drugs, not dietary supplements, and are not for human or veterinary use.
