Modification
Free termini.
An amphiphilic nonapeptide first isolated from cerebral venous blood. No specific DSIP receptor or gene has been definitively isolated; its molecular target remains poorly defined.
Research Focus
Studied in sleep / EEG (delta-wave) neurophysiology and circadian-rhythm research.
Lyophilized
-20°C
protect from light; stable many months.
Reconstituted
2-8°C short-term
-20°C longer; avoid freeze-thaw.
Amphiphilic; alpha-Asp vs beta-Asp isomerization is relevant to identity; protect from light.
