Frequently Asked Questions

Q: What is the minimum purity level required for NAD peptide to be suitable for research-grade applications?

A: For research-grade applications, particularly in enzymatic assays and cell culture studies, NAD peptide should have a minimum purity of ≥99.0% as verified by HPLC analysis. Lower purity levels introduce unknown impurities that can interfere with enzymatic reactions, alter cellular metabolism measurements, and compromise experimental reproducibility. Our product consistently exceeds this threshold, with each batch independently tested and documented in the certificate of analysis.

Q: How does the lyophilized powder stabilization method affect the shelf life and handling of NAD peptide?

A: Lyophilized powder stabilization removes water content to below 3%, significantly reducing hydrolysis and degradation rates. When stored at -20°C under desiccated conditions, the shelf life extends to a minimum of 24 months without detectable purity loss. Handling requires equilibration to room temperature before opening to prevent moisture condensation, and reconstitution should be performed with sterile, endotoxin-free water for research applications. This stabilization method eliminates the need for cold chain storage during short-term handling, reducing logistical complexity for procurement teams.

Q: What documentation should a buyer request to verify the quality and authenticity of NAD peptide from a supplier?

A: Buyers should request a comprehensive certificate of analysis that includes HPLC purity data with chromatogram, mass spectrometry confirmation of molecular weight, amino acid analysis for composition verification, endotoxin testing results using the LAL method, and heavy metal screening report per ICH Q3D guidelines. Additionally, request the supplier's ISO certification documents, cGMP compliance statements, and stability study summaries under recommended storage conditions. Third-party testing reports from independent laboratories provide an additional layer of verification and support regulatory submissions for research and development applications.
