Hey everyone I see a lot of newer researchers stressing out about whether their vials need to be in the freezer or the fridge. I wanted to put together a simple breakdown based on what standard lab manuals usually recommend for keeping things stable before and after reconstitution. Basically any lyophilized powder should live in the freezer for long term storage if you want it to maintain integrity for months. Once you add your liquid and reconstitute it for your assays it needs to move straight into the refrigerator to slow down degradation. Try to avoid letting the temperature fluctuate too much since constant thawing ruins peptides fast. I hope this helps clear up some confusion for anyone just setting up their workspace. Feel free to drop any questions below and we can work through them together.
