Handled correctly, stability holds
All peptides are supplied as sterile, lyophilized powder and are stable when handled correctly.
Store vials in a cool, dry place away from heat and direct sunlight.
For optimal longevity, keep lyophilized peptides refrigerated to help maintain integrity.
Use an appropriate research diluent (for example, BAC water). Store the reconstituted solution in the refrigerator and use within 20–30 days for best stability.
Minimize exposure to moisture and repeated freeze–thaw cycles. Follow your institution's safety procedures when handling research materials.
