Hi there!

I have some experience with perforated patch-clamp. For Nystatin you 
should simply to take care to work in darkness, when possible (it is 
UV-sensitive...). Stock solution should be stored (-20ºC) in those color 
eppendorf tubes or wrapped with Aluminum foil, to keep them away from 
the UV rays....

I could give you more advices, if you tell me exactly which kind of 
cells are you trying to patch (slices or cell-culture?).

I personally find Anphotericin B better for perforated patching! :P
