Dissolving Nystatin

Hi,

Does anyone have protocol to make a nystatin stock solution in DMSO.

I've been dissolving 0.1gram of nystatin in 1ml of DMSO (the solution is clear and yellow) and then adding 0.5ul into my 1 ml of recording solution.  The solution IRS doesn't turn yellow or turbid like people have reported.

I'm just wondering if there is  a problem with the way i'm making my stock.

Any help will be greatly appreciated.
