CryoJane Tape-Transfer Process

The CryoJane® Tape-Transfer System creates frozen sections as thin as 2 microns with the same quality as sections cut from paraffin blocks. Sections are wrinkle-free, uncompressed, and fully intact when bonded to the microscope slide. The CryoJane uses adhesive coated slides and adhesive tapes to capture sections instead of using an anti-roll plate or brush. CryoJane is suitable for routine cryosections and is indispensable for sectioning difficult tissues including fatty breast and undecalcified bone.

  • Preserves sample morphology
  • Increases quality, reduces repeats and streamlines workflows
  • Allows fast and virtually effortless serial sectioning

With the CryoJane Tape-Transfer System, thin tissue sections remain unflawed even after mounting. This makes CryoJane ideal for applications that require perfectly thin sections to clarify structural relationships and reveal morphological detail. The CryoJane Tape-Transfer System is adaptable to most cryostats on the market.

  • Sections can be fixed "anhydrously" to preserve virtually all fine structures present in the snap-frozen block of tissue
  • Water-soluble enzymes, antigens and nucleo-proteins are preserved in situ
  • With appropriate fixation and staining, true localization of enzyme and antigen activity can be visualized
  • The bond between the section and the slide is solvent resistant and permanent, preventing section loss during staining


  • Histological stains
  • Immuno stains
  • In situ hybridization
  • Laser Microdissection and Laser Capture Microdissection
  • Frozen tissue arrays and other molecular diagnostic studies


  • Ideal for fatty tissues - Keeps fatty tissues such as skin, breast & undecalcified bone together. Excellent for serial sections of brain.
  • Consistent results - Consistent results help operators maintain productivity and preserve tissue samples
  • Safe for protocols - 8 millisecond, long-wave UV (360 nm) is safe for protocols such as In situ Hybridization
  • 2-60 µm - Sections can be cut between 2-60 um in thickness
  • Temperature controlled - Temperature controlled pad for optimal section transfer conditions

Products required by the CryoJane System

Protective Oil arrow10Protective Oil Accessories Kit

Oil in the bath is maintained at –8°C inside the cryostat and will not melt the tissue when brushed on the frozen block-face. Frozen blocks coated with this protective oil can be stored for up to one year in a freezer without dehydration.

The Protective Oil Accessories Kit includes the following: Temperature controlled Oil Bath, 4 oz Bottle of Protective Oil, and Oil Brush. Please note that when purchased separately from the CryoJane system, installation of the Protective Oil Bath Accessory requires that the CryoJane® system be returned to Electron Microscopy Sciences.

cryogenic gelmsdsCryo-Gel Water-Soluble Embedding Medium arrow12Cryo-Gel

  • Replaces the messy "runny" embedding media.
  • Easy to use.
  • Stick to where you want it.
  • Will not run – No waste

It is a highly viscous, water-soluble embedding medium for frozen sections that "stays put". The gel is packaged in a pump-dispenser bottle that can instantly dispense the gel in any position. The dispenser has a built-in"guillotine" that cleanly severs the gel from the pump spouts and prevents any "stringy" medium from pulling away when the bottle is removed. Simply dispense gel on room temperature blockholder. Use cold heat extractor to form a base layer. Dispense additional gel. Place the tissue on top of gel. Use cold heat extractor to freeze tissue and form block. Each bottle contains 4.3oz (159ml), 12/case.

msdsCureMount™ - Mounting MediumCureMount™ - Mounting Mediumarrow12CureMount™ – Mounting Medium

CureMount™ is a UV curable mounting medium of low viscosity for use with all dehydrated sections. CureMount™ is a polymer that cures to a refractive index of 1.55. It closely matches the refractive index of dehydrated tissue. The coverslip can be optimally positioned and cured under UV fluorescent illumination. The coversliped slide is "dry" in less than 30 seconds. The coverslip can easily be removed by heating the slide briefly, soon after curing or after a longer time by immersing in xylene. All unstained tissue elements and the cured polymer will be invisible, making the stained elements stand out in exquisite detail. Comes in brown glass dropping bottle, 60 ml.
