Hey guys, I've ran into the following problem. I want to use carboxy-PTIO reagent in my cell experiments and I can't find conclusive data on how to store the its stock solution. In the literature it is written that it is very well soluble in water but not stable for longer than a day, at the same time it seems to be stable in DMSO but it is not clear if it is soluble in DMSO well enough. I purchased a commercial 25 mg sample, but it seems that it won't be possible to take out the product and weigh it properly. How do you work with this reagent? Thank you!
Hello Maria,
You can see the product information from Cayman Chemical .
Here is product information sheet and hope to help you.
Hello Maria,
Did you solve the C-PTIO store problem? I'm in the same as you?
it seems highly soluble in DMSO but what about the stability?
It seems that the company producing carboxy-PTIO also doesn't know anything about the stability in DMSO at low temperatures. They said they can guarantee that it's stable for two weeks, but after that they don't know. I rushed my experiments and it seemed to be ok. But I never used the aliquoted amounts that left after that experiment. If you know something later, please let me know.
