I understand that the typical advice is to store in a freezer before reconstitution and then in a fridge thereafter.
Storing peptides at room temperature.
Storage guidelines for lyophilized peptides upon receiving the lyophilized peptide store at 4oc or colder and away from bright light.
Here is a breakdown of proper storage procedures for both dry and liquid peptides.
Reseal the vial tightly.
Peptides should not be kept in solution for long periods of time.
For long term storage peptides should be stored in lyophilized form at 20 c or preferably at 80 c with desiccant in sealed.
Each time you use some of the peptide remove the container from cold storage and allow it to equilibrate to room temperature or slightly warmer.
Lyophilized peptides are stable at room temperature for days to weeks but for longer term storage it is safer to store at 20oc or colder.
Storage of reconstituted peptides.
Lyophilized peptides are stable at room temperature and can be kept in their initial packaging for several days to weeks.
Store the remaining peptide in a freezer preferably below 20 under dry conditions.
Storing a dry peptide.
The stability of custom peptides is not defined by sb peptide and can be assessed upon request.
Otherwise peptides can be stored at 4 c or colder according to your preference and to experimental.
If stored at room temperature they may begin to degrade after as little as 24 hours.
Peptide stability guidelines.
This will reduce the uptake of moisture that is present in the surrounding atmosphere.
Peptides are stable at room temperature for days to weeks but for long term storage 20 c is preferred.
However i have heard of many reports of people storing it at room temperature both before and after reconstitution without the peptide experiencing any.
When preparing your peptides for use in an experiment or assay follow the guidelines below.
Before using the peptide remove from cold storage and allow the peptide to equilibrate to room temperature before removing the lid of the container.
Contamination with moisture will greatly decrease long term stability of solid peptides.
Therefore we recommend storing them in the fridge as soon as possible after mixing.
When a peptide is shipped in a dry form there are two storage options.
Weigh out the desired quantity of peptide quickly.
First is leaving the peptide at room temperature for a short term storage solution but this only works if the peptide is room temperature stable.
Additionally it is important to avoid repeated freeze thaw cycles.
This can increase the peptide s susceptibility to degradation.
Warm the peptide vial to room temperature before opening.
Once the peptides have been mixed or reconstituted into a liquid solution they must be refridgerated at a temperature of between 2 8c.
Peptides are shipped at room temperature and are highly stable at lyophilized form in sealed bags why in sealed bags.
When storing peptides for months or even years freezing at 80c 112f is optimal in order to preserve the peptide s stability.
