Description_x000D_ General description_x000D_ 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._x000D_ Application_x000D_ 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._x000D_ Features and Benefits_x000D_ • Colored PolyFreeze (blue, green, yellow) makes differentiating multiple specimens easy during sectioning and staining_x000D_ • Experience less curling, less ice artifacts, faster freezing with PolyFreeze
