General description

Mowiol® is a water soluble hydrocolloid mucoadhesive based on poly (vinyl alcohol). Mowiol® at pH 8.5 has a couple of advantages over other mounting media:
  • its a liquid when the sample is mounted and solidifies after several hours, forming a permanent bond between the coverslip and slide
  • fluorescence is stable when held in dark and at 4oC.

Application

Mowiol® is used as an embedding medium for preserving stained cell dishes in the study of siRNA array production of HeLa cells. Mowiol® is also reported to be used as a mounting medium in:
  • design of TSAR and its applications
  • detection of the secreted and cytoplasmic fractions of IpaB, IpaC and IpaD by lysozyme permeabilization
  • fluorescence recovery after photobleaching (FRAP).

Mowiol® may be used as a coating for sensors based on piezoelectric quartz crystals. Another probable use of Mowiol® is during the study of super fluorescence imaging of biocompatible carbon dots.
