Descripción

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 4^oC.

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.
