If you are dealing with peptides, then you have to understand that storage differs in regards to the specific type. There are some, which require storage in dry form, while others demand storage in liquid form. It is vital for every researcher to know how to properly store peptides, especially during instances when you are dealing with different forms at the same time.
Below, is a short guide, summarizing the proper storage of research peptides:
How to store a dry peptide
When you get your peptide in dry form, you have two options for storage. The first option is to leave the peptide, as it is, at room temperature, as a short-term storage solution. However, this is only possible if the peptide is stable, at room temperature.
The second option is applicable if the peptide is not stable at room temperature, during which you will have to cool it to retain its stability for the short term. Keeping the peptide below 4 degrees will be sufficient to store it for a few months, but if you are considered long storage, then it should be stored in temperatures below 20 degrees.
Storing peptides as solutions
Storing liquid peptides over a long period, is never an easy task. In most cases, however, refrigerated storage may be sufficient in the short term, but if long term storage is required, then it is recommended to freeze the peptide, and keep it at temperatures below 200C. Under such conditions, the peptide will be safe from degradation and degeneration, thus allowing it to maintain its stability, and be used to accurate results in the long term.
It is recommended that researchers should only order the peptide quantities they need to use, so as to avoid instances of long storage periods. This is because there is always a chance of the peptide’s integrity being compromised by consistent freezing, and thawing cycles when kept in refrigeration for long durations.
