General description

Eukitt® Quick-hardening mounting medium, or Poly(butyl methacrylate-co-methyl methacrylate), is a mounting medium for microscopy, containing 45% acrylic resin and 55% xylenes. It is a special-purpose adhesive, sealant, and specimen preservative that can be used manually and in automated cover-slipping equipment, glass, non-plastic, and other non-reactive materials.

Application

  • It has been used in histomorphometry to study the use of gambogic amide for augmenting skeletal adaptation to mechanical forces without inducing hyperalgesia.
  • It has been used in immunohistochemistry and immunofluorescence to document the global location of coxsackievirus and adenovirus receptors in the mouse brain.
  • It has been used in immunocytochemistry to study the function of matrix metalloproteinases in regulating cancer invasiveness.

Features and Benefits

  • Spreads quickly and evenly without forming any air bubbles.
  • Non-yellowing, unaffected by cold, and stays optically clear for over 10 years.

Physical properties

Fast-drying (20 minutes), Refractive index close to that of glass (1.510), chemically neutral, little sensitivity to water, no reaction to staining, temperature limits: 42°C-17°C, not affected by ultraviolet light, non yellowing, unaffected by cold, stays optically clear for over 10 years, can be used in place of epoxy resins for mounting petrographic thin sections, used in fluorescence dyes in bones.
