Storage and Handling
Store lyophilized Melanotan-2 according to proper laboratory storage practices.
- Keep lyophilized material in a cool, dry environment
- For long-term storage, maintain at -20ยฐC / -4ยฐF
- Once reconstituted, store at 2โ8ยฐC / 36โ46ยฐF
- Use promptly after reconstitution according to internal laboratory protocols
- Maintain aseptic handling practices
- Avoid repeated freeze-thaw cycles
- Protect from unnecessary light, heat, and moisture exposure
Storage conditions may affect peptide stability, so researchers should follow appropriate handling standards for lyophilized peptides.
