I am starting to work with Pyrvinium pamoate salt hydrate and wanted to know how I have to store this chemical once it is dissolved in DMSO? I bought this compound from Sigma, but they got it from Pfizer and cannot tell me how to store it. The only information they have is that the powder should be stored at room temperature, but usually we freeze our inhibitors after we dissvolve them. Does anyone have experience with this compound and would you store it at room temperature also when dissolved and if so, how long?
