question for anyone who is able to answer... I have some frozen peptides in my freezer that have been sitting there for 3+ years. I had pretty good success using them a while back and was wondering if they are still good after this much time?
I've been looking into the storage question, but there's nothing too definitive. I think the best answer you'll get is that there may be some degradation, though there doesn't seem to be evidence that it's substantial in that time frame if the temperature variations were kept small.
Did you ever encounter a déjà vu? It's basically a feeling you've seen or heard something like this before, even though you didn't... The false memories are basically just like that. But more importantly...
When selecting peptides for custom synthesis, several important factors should be considered during the design process. These considerations include sequence length, solubility and sequence stability.
