Peptide buying FAQ
Which is better: lyophilized powder or pre-mixed solution?
Lyophilized powder generally offers longer stability and is preferred for research. Pre-mixed solutions offer convenience but may have shorter shelf life. Choose based on your application.
How do I verify a peptide's purity before purchase?
Request the Certificate of Analysis (COA) from the supplier. Reputable vendors share HPLC chromatograms and mass spec data. Compare purity percentages (typically >98%).
What is the recommended way to store research peptides?
Store lyophilized peptides in a cool, dry place away from light. After reconstitution, refrigerate and use within the recommended timeframe. Always follow the supplier's instructions.
