Tissue freezing medium, PolyFreeze, Sigma-Aldrich®

Supplier: SIGMA ALDRICH MICROSCOPY

Tissue samples may be snap frozen using PolyFreeze with isopentane and liquid nitrogen, dry ice (slush/slurry or bunker), or in a cryostat. PolyFreeze media do not cause autofluorescence and can easily be washed away during tissue fixation when rinsed prior to staining. Once rinsed off the slide, there is no trace of the support matrix to interfere with staining or immunohistochemistry (IHC) reactions.
