To maintain the accuracy of laboratory results, it is very important to store peptide product properly. If storage is done properly than peptide product can be preserved for many years saving it from degradation, contamination or any sort of oxidation. According to top site sciencedirect.com, every peptide is prone to a different level of degradation. So implementing peptide storage is a must to increase the longevity of peptides.
When the peptide is supplied, it should be immediately transferred to dry and cold place to avoid contamination. It can be kept in the refrigerator under 4-degree Celsius if to be used in short duration. Some peptides like lyophilized, storing at room temperature will be enough if used immediately.
To store peptides for a longer duration, freezing should be done in -80 degrees to preserve the stability of peptides. Also, the freezing cycle repetition unnecessarily should be avoided due to peptide’s chances of degradation. Apart from this, you should avoid the use of frost free freezer for storing peptides as there is a regular change in temperature during the process of defrosting cycle.
Avoiding Moisture Contamination And Oxidation
Peptides are to be protected from both moisture and air to avoid any contamination or oxidation. If you are using peptides for research immediately after removing from freezer, there is a chance that it will contaminate after coming in contact with moisture. To avoid any moisture inside the container or on the surface of the container, better to let it come to room temperature before any usage for research.
Also, peptide container should be airtight, not letting any air to pass through to avoid oxidation process. When the required amount for research is taken, rest of the peptide product in a container should be sealed properly in a dry environment before letting it get oxidized.
Containers Storing Peptides
The container to be used for peptide storage should be properly cleaned and dried. It should be required size and chemical resistant to avoid any chemical reaction. The container can be both plastic or glass material. In plastic generally, polypropylene is used as it is chemical resistant and translucent. For the peptide storing container, glass is a perfect material as it is both clear and chemical resistant. But during shipping, Its avoided as to safeguard from any sort of breakage.
Peptide Storage in Solution
If you want to store peptides with utmost accuracy, then storing of peptides in solution should be avoided. If you compare with other storage option, the shelf life of solution storage is very less. Also, it is vulnerable to bacterial degradation very easily. Few peptides containing Asp, Met, Gln, Cys have a very short lifespan in solutions. The stability of solution storage is only for a week max.
General Tips To Store Peptides
· Peptides should be stored in dry and cold place.
· Regular thawing and repeated freezing cycle should be avoided.
· For longer duration, storing peptides in solution should be avoided
· Overexposure of peptides to air should be avoided
· Usage of peptides should be done on the basis of research requirement.
· Continuous exposure of peptides to light should be avoided.
