So essentially, I'm trying to find the temperature at which growth hormone (GH) denatures. I've got a box of it and it says "refrigerate at between 2'C to 9'C". I'm keeping it at room temperature (it's not for use atm), but would like to find out how to know at what temperature GH would break up. I know GH is made of 191 amino acids, and there's more info on the wiki: https://en.wikipedia.org/wiki/Growth_hormone Is there like a info sheet I can refer to find the denaturing point of a molecule? Generally not entirely sure how to go about this, so any help is much appreciated!
