DSIP (delta sleep-inducing peptide) is a nonapeptide with the sequence Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu (WAGGDASGE). PubChem lists its molecular formula as C35H48N10O15, with a molecular weight of about 848.8 g/mol. It was first isolated in the 1970s and remains a referenced research peptide.

KYVEC supplies DSIP as a lyophilised (freeze-dried) powder in a sealed, labelled vial, packed in our signature KYVEC black box. Each label shows the product name and quantity, so stock can be logged and tracked in your lab inventory as soon as it arrives.

Storage and handling: Store unopened vials in a cool, dry place away from light. For long-term storage, refrigerate (2–8°C) or freeze (−20°C). Once reconstituted for laboratory use, keep refrigerated and avoid repeated freeze–thaw cycles. Handle with standard laboratory PPE.
