Nystatin and yeast

[Ingrid Rojas]

Hello,
Does anyone have or know where i can read a method for inactivation of
yeast with nystatin. When we try to filter it (dissolved in DMFA) the
most nystatin was retented on the filter. Maybe something is wrong
with dissolution of nystatin

All help would be very appreciated. Thanks Jorge Valdes
