Buy DSIP research peptide (15 mg vial or 10-pack) for in-vitro laboratory research. Every lot is tested by HPLC and mass spectrometry and comes with a batch-specific Certificate of Analysis.
About DSIP
DSIP is a synthetic nonapeptide (Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu) studied in cell-culture models for receptor-binding interactions. Alchemy Gold Research supplies DSIP as a lyophilized powder for in-vitro laboratory research. Every lot is tested by HPLC and mass spectrometry and ships with a batch-specific Certificate of Analysis (COA).
Research background
In the research literature, DSIP serves as a tool compound for studying receptor-binding interactions in cultured cell models. Work has examined modulation of GABA-A receptor activity, hypothalamic-pituitary axis signaling, and neuronal excitability at the molecular level, along with stress-response pathway biochemistry. Most published work on DSIP is preclinical. It has not been approved for human or veterinary use, and it is supplied here for laboratory research only. Researchers typically run it alongside vehicle and positive controls and keep to a single lot across an experiment series.
Studied research pathways
- GABA-A receptor modulation. Cell-based assays examining modulation of GABA-A receptor activity.
- Hypothalamic-pituitary axis signaling. Cultured cell models used to study hypothalamic-pituitary axis signaling.
- Neuronal excitability. Molecular-level studies of neuronal excitability in cell-culture models.
Quality and documentation
Every lot of DSIP is tested by HPLC for purity and by mass spectrometry for molecular identity, and it is released with a batch-specific Certificate of Analysis (COA) that lists the lot number, test date, purity and mass result. Testing is carried out by an independent third-party laboratory. The exact values for the lot you receive are printed on its COA.
Storage and handling
Store the lyophilized powder at −20 °C (−4 °F), protected from light. Keep the vial sealed until you are ready to use it, and let it come to room temperature before opening to limit moisture condensation. Solvents, concentrations and handling protocols are set by your research team and your institution's safety procedures.
Frequently asked questions
- Is DSIP approved for human use?
- No. DSIP is sold for in-vitro laboratory research only. It is not a drug, food or supplement, and it is not approved by the FDA for human or veterinary use.
- What purity do you test for?
- Every lot is tested by HPLC, and the product specification is ≥98% purity. The measured value for your lot is printed on its batch-specific COA.
- Where do I find the COA?
- A batch-specific COA accompanies each lot. If you have a question about a COA, contact us and include the lot number.
- Who can buy DSIP?
- Qualified researchers and laboratories that accept our Research Use Only (RUO) policy. The policy page lists the conditions of purchase.
- Is DSIP a fragment cleaved from a larger protein?
- No. DSIP is a synthetic nonapeptide produced by chemical synthesis, with the sequence Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu.
