DSIP
DSIP is a synthetic nonapeptide composed of nine amino acid residues (sequence Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu). It is studied within sleep-regulation and circadian-signaling research, where it serves as a subject in neuroendocrine and central-nervous-system signaling investigations. In preclinical and in-vitro models, researchers characterize its interactions with neurotransmitter systems and hypothalamic signaling pathways and examine its relationship to delta-frequency electroencephalographic activity strictly as a laboratory research subject.
Supplied strictly for laboratory and scientific research use by qualified professionals. Third-party tested; identity and purity verified by HPLC and mass spectrometry, with a lot-specific Certificate of Analysis available on request.
