COA and Quality Assurance
Spark Peptide provides a lot-specific Certificate of Analysis for every DSIP lot. Each COA documents identity by HPLC and mass spectrometry, purity, sterility (USP <71>), and endotoxin levels (LAL), plus lot-specific storage guidance. Testing is conducted by independent third-party laboratories including Janoshik. COAs are available on the Lab Tests page.
Handling and Storage
Store lyophilized DSIP at -20°C in a tightly sealed vial, protected from light and moisture to help preserve peptide stability. When preparing a working solution, use an appropriate sterile reconstitution solution or compatible laboratory buffer in accordance with validated laboratory procedures. Depending on the needs of the study, prepared solutions may be maintained under refrigerated conditions for short-term use or frozen for longer-term laboratory storage, with aliquoting commonly used to help maintain sample integrity during repeated use. Always follow institutional biosafety, laboratory handling, and disposal requirements.
Legal and Regulatory Disclaimer
DSIP is supplied strictly for laboratory research purposes only and is not approved by the FDA or any regulatory authority for human use, veterinary use, clinical administration, therapeutic applications, or diagnostic procedures. Its safety and efficacy in humans have not been established. Purchasers are solely responsible for compliance with all applicable laws and institutional biosafety policies.
