The Best Ways To Store Your Peptides

Do you use peptides for your research work? Peptides are short or long chains of amino acids linked together by peptide bonds. They are widely used for research work in plants and animals. Their stability is very much dependent on the composition and sequence of amino acids in them. The peptides, if not stored properly, will lose its stability and potency which would render them unreliable for research works. If you use peptides for your work, then you can understand more about their proper storage and handling at https://americansciencelabs.com/follistatin-344.

Most peptide manufacturers specify how to store their products clearly on the product cover, leaving little room for ambiguity. Yet, it would be ideal if you could glance through these general guidelines we have compiled with the help of sciencedomain.org.

Some peptides are best stored in dry form till they are mixed at the time of using while others are to be stored in liquid form to remain stable. Let us see how dry and liquid peptides can be stored for longer shelf-life.

Dry peptides
Most peptides are shipped at room temperature and can remain stable at that temperature for up to a couple of weeks. But, make sure that that it is a room temperature stable one. Else, they need to be stored in cooler temperatures (>4-degree centigrade) for storing for a few months. If the peptides need to be stored for longer periods, say more than four months, then ensure that they are kept in a freezer at a temperature which is not more than -20-degree centigrade.

Keeping them away from direct light is another important consideration that you must keep in mind while storing peptides. Light can decay peptides – whether they are stored at room temperature or at cooler temperatures – and make them unstable. Another fact that you should remember while using peptides is that they are easily contaminated by the moisture in the air. So, whenever you need to take some peptide out of the container, make sure that the container has come down to the room temperature before opening it. To avoid exposing the content to the warmer air outside, quickly measure the amount of peptide you need to carry out your work and close the container. Once the required quantity has been taken out, reseal your vial and return it to the freezer for storing.

Liquid peptides
Storage of liquid peptides for longer periods is challenging as they tend to undergo oxidation and degradation. Freezing them below -20-degree centigrade is the best option available. However, it would be best to measure out and store them in multiple containers as per your research requirement. This would avoid repeated freezing and thawing of the same peptide which would affect its stability. Also, make sure that you are not using a frost-free freezer as they tend to have unstable temperature owing to the repeated on and off cycles built-in to their design to prevent the formation of frost.

Care must be taken at the time of ordering itself to ensure the proper storage of peptides for prolonged shelf-life.
