Goodmorning everyone!

I am using the IWP-2 inhibitor (IWP-2 inhibits the WNT pathway at the level of the pathway activator Porcupine) on melanoma cell line FO1 with a 20 µM concentration but when I add it to the medium into the wells it is not completely soluble and form visible precipitates, do you have any suggestion to avoid this problem?

Thank you very much in advance and have a good day!

Serena
