Peptide Handling and Storage
Peptide handling and storage
Peptides are shipped at ambient temperature by standard shipment process (FEDEX, USPS, DHL…).
Quantum Peptides provides lyophilized powder delivery for their peptides. The observable volume of powder may vary among two tubes containing identical quantities. It is essential not to view this difference skeptically. Certain peptides, especially short sequences, exhibit high hygroscopicity, leading them to appear as a gel or be barely visible.
Short-term storage
Lyophilized peptides are stable at room temperature and can be kept in their initial packaging for several days to weeks. Otherwise, peptides can be stored at 39 °F or colder for up to 3 months, according to your preference and to experimental requirements. Peptides should be protected from intense light.
Long-term storage
We recommend storing peptides at < -4 °F or -112°F for a period longer than 4 months.
Storage of peptides in solution
When preparing stock solutions, it’s recommended to use dry (anhydride) organic solvents to prevent premature hydrolysis. The stability of peptide aliquots can vary, lasting from weeks to months. A widely accepted guideline is that peptides in solution remain generally stable for 1-2 weeks at +39°F, 3-4 months at -4°F, and up to 1 year at -112°F. Understanding these considerations is vital for researchers. Additionally, tools like a peptide calculator can assist in precise measurements, contributing to the overall handling and stability of peptides in various applications.

Handle peptides with care!
Quantum Peptides acts on behalf of its clients to furnish their research peptides. Quantum Peptides neither assesses the toxicity of peptides nor provides safety datasheets. Consequently, it cannot be held accountable in the event of an accident.
Nevertheless, we recommend our clients to handle peptides with caution. Lyophilized peptides can be volatile. Some peptides can be toxic for humans, animals or the environment. The use of laboratory personal protective equipment, such as gloves, masks, and safety glasses is mandatory. Finally, it is very important to handle peptides in a clean and well-ventilated room.
Ensure that your peptides are optimally stored and enjoy your experiments!

FAQs
Peptides are generally recommended to be stored in a cool and dry environment, but refrigeration is not always necessary. It depends on the specific peptide and its stability characteristics. Always refer to the supplier’s guidelines for storage recommendations.
The stability of peptides varies, but they are often stable at temperatures ranging from -4°F to +39°F (-20°C to +4°C). However, this is a general guideline, and it’s crucial to check the specific stability information provided by the supplier for each peptide.
Yes, peptides can be stored in the freezer, and it is a common practice to enhance their shelf life. Peptides are often stable for longer periods when stored at temperatures below -4°F (-20°C). Again, check the specific storage recommendations provided by the supplier.
Peptides can be sensitive to heat, and exposure to high temperatures may lead to degradation. It is advisable to store peptides in a cool environment and avoid prolonged exposure to elevated temperatures. Always follow the recommended storage conditions to maintain the stability and integrity of the peptides.
