Handling and Storing Peptides the Right Way
Handling and storing peptides the right way is vital for their longevity, as well as for your chances of getting good results with them. It is regrettable, however, that most people never bother to know how to properly handle peptides so that they can get the most from them. Below is a brief guide on how you should handle and store peptides using best practices:
How to Handle Lyophilized Peptides
Lyophilized peptides should be stored at -180C if you want them to retain their maximum stability. Since these peptides are always hygroscopic, they should be warmed to room temperature inside desiccators before they are opened and weighed. Their stability can be reduced upon absorbing moisture, and this may reduce their overall content. Be sure to weigh the peptides quickly and reseal the vial to prevent them from absorbing water.
How to handle peptides in solution
Peptides in solution are always less stable as compared to those in lyophilized powder form, and they are always prone to degradation by bacteria. To stop this from occurring, it is recommended that the peptides are dissolved in sterile purified solvents. Alternatively, you can sterile filter the peptide solution using a 0.22 um filter. Try as much as possible to avoid regular thawing and freezing cycles if the peptides are in solution form. All the peptide solutions remaining for sale should be aliquoted and stored at temperatures below -180C.
Handling peptides during shipping
Since most peptides will remain stable when in lyophilisate at room temperature, there may be no need for refrigeration when being transported a short distance. But extended exposure to warm temperatures should be avoided during shipping. Once the peptides are delivered, long term storage is recommended at temperatures below -180C. Storing peptides in this manner will give them the longevity they need to stay stable for many more years to come.
