DSIPSleep peptide

DSIP price comparison

DSIP (delta sleep-inducing peptide) is a short endogenous nonapeptide first isolated from cerebral venous blood, widely catalogued as a neuropeptide research term. In laboratory settings it is studied for its interactions with sleep-related and neuroendocrine signaling in animal and in-vitro models. This index tracks research-use-only (RUO) vendor pricing for DSIP so researchers can compare cost across suppliers.

Why compare $/mg for DSIP?

Per-mg prices for DSIP vary because vendors differ in synthesis scale, stated purity, fill quantity per vial, and lot testing overhead. Comparing normalized $/mg across suppliers helps a researcher gauge whether a listing is competitively priced rather than reflecting a smaller fill or lighter documentation.

Reading the COA

For DSIP, confirm identity by mass spectrometry against the expected monoisotopic mass of the nonapeptide sequence (Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu), and check that reported HPLC purity meets a stated threshold (commonly 98%+ for research material). Watch for common synthesis-related impurities such as truncated or deletion sequences and residual TFA counterions; a COA should show the HPLC chromatogram and MS trace, not just a summary percentage.

FAQ

How is lyophilized DSIP typically stored in a lab?
As a lyophilized powder, DSIP is generally kept sealed and protected from moisture and light, stored cold (often refrigerated short-term or frozen for longer periods) per the vendor's stated conditions. It is a research chemical, and any storage guidance on the COA or product page refers to preserving material integrity for laboratory work, not to human use.
What is a COA and what should I check for on a DSIP certificate?
A Certificate of Analysis (COA) is the vendor's lot-specific quality document. For DSIP, check that it identifies the peptide by mass spectrometry (matching the expected mass), reports HPLC purity against a stated threshold, lists the lot/batch number, and ideally includes the actual chromatogram and MS data so identity and purity can be independently assessed.
Why do per-mg prices for DSIP differ so much between vendors?
Differences come from synthesis batch size, stated purity grade, the amount of peptide per vial, counterion content, and the depth of analytical testing documented. A lower headline price can reflect a smaller fill or less rigorous testing, which is why normalizing to $/mg and reading the COA together gives a clearer comparison.
