Peptides are supplied lyophilised (freeze-dried) because the dry powder is far more stable than a solution. Correct storage protects your results.
Before reconstitution
- Store vials at −20 °C for long-term storage.
- Keep them away from light and moisture.
- Lyophilised peptides tolerate room temperature during normal transit.
- Let a vial reach room temperature before opening to avoid condensation.
After reconstitution
- Keep solutions refrigerated at 2–8 °C.
- Bacteriostatic water contains 0.9% benzyl alcohol, which limits microbial growth in multi-use vials.
- Avoid repeated freeze–thaw cycles; aliquot if you need to freeze.
Choosing a solvent
Most peptides dissolve in bacteriostatic or sterile water. Some, such as certain IGF analogues, dissolve better in dilute acetic acid. Both are available in our lab supplies range.
