DSIP
This is a short neuroactive peptide reference supplied as a lyophilised powder for central-nervous-system research.
Typical applications include receptor-binding assays, blood-brain-barrier permeability work and neuroprotection models.
This listing is the 5mg presentation of DSIP. Independent product testing reports reverse-phase HPLC purity of ≥99% and LC-MS confirmation against the expected mass. Vials ship sealed and desiccated, are stable at ambient temperature in transit, and should be stored at −20 °C on arrival. Reconstituted material is kept refrigerated and used within the window defined by your own protocol. Orders placed before the daily cut-off are typically dispatched within 24 hours from the UK, with tracked delivery across the UK and the European Economic Area.
- What purity is DSIP tested to?
- DSIP has been independently tested by reverse-phase HPLC to ≥99% and identity-confirmed by LC-MS.
- Is a certificate of analysis available for DSIP?
- DSIP has been independently tested by HPLC and LC-MS through a partner laboratory, with representative certification documenting the results where published.
- How should DSIP be stored?
- Store the sealed, lyophilised vial at −20 °C and keep it desiccated. The powder is stable at ambient temperature during transit. Once reconstituted, material is refrigerated and used within the timeframe your protocol specifies.
- Do you ship DSIP to the UK and Europe?
- Yes. Orders are dispatched from the UK, typically within 24 hours of payment clearing, with tracked delivery to the United Kingdom and to the European Economic Area countries we currently serve. UK pricing is in pounds sterling and EU pricing is in euros.
- Is DSIP suitable for human or veterinary use?
- No. DSIP is an unlicensed reference standard supplied strictly for in-vitro laboratory research by qualified professionals. It is not a medicine, dietary supplement or cosmetic, and must not be administered to humans or animals.
