General description

PolyFreeze Tissue Freezing Medium does not result in autofluorescence. It is easy to cleanse at the time of tissue fixation, when washed before staining. After washing the medium, there will be no trace of the support matrix to hinder with staining or immunohistochemistry (IHC) reactions.

Application

A support matrix or form of embedding medium for frozen sectioning. This medium freezes quickly supporting the tissue for sectioning at 3 μ and up with no cracking of the matrix at temperatures from -8 °C to -25 °C. Snap freeze using PolyFreeze with isopentane and liquid nitrogen or dry ice (slush/slurry or bunker). Store specimens frozen in PolyFreeze in liquid nitrogen canisters or in airtight containers in a -80 °C freezer.

Features and Benefits

  • Colored PolyFreeze (blue, green, yellow) makes differentiating multiple specimens easy during sectioning and staining
  • Experience less curling, less ice artifacts, faster freezing with PolyFreeze
