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.Standard frozen sections at 3-6 mum are easy to obtain and mount on glass slides for drying and/or fixation prior to staining, while thicker sections can be taken as required. Sections will flow freely under an anti-roll device, allowing flat sections to be picked up from the knife-edge. Sections can be either fixed immediately in the fixative of choice or air dried for later fixation and staining. Drying or fixing the slides in the cryostat for specific procedures will not affect the PolyFreeze medium.um are easy to obtain and mount on glass slides for drying and/or fixation prior to staining, while thicker sections can be taken as required.
