Cryostat
Section Preparation Aids
CryoJane™ The
Cryostat Frozen Sectioning Aid System
With the CryoJane™ Tape-Transfer System in your existing cryostat, you will be able to routinely obtain flat, thin, wrinkle-free, frozen sections.
- Offers morphological detail equal to paraffin!
- Sections as thin as 2 microns consistently!
- Transfers flat sections!
- No folds or compression in the sections!
- The system can be easily installed in virtually all cryostats!
- Easy to use & cost effective.
TheCryoJane™ Tape -Transfer System achieves frozen sections
of paraffin quality as thin as 2 microns, wrinkle-free, uncompressed,
fully intact and bonded to the microscope slide… in less than
3 minutes. The frozen section is captured on a cold tape window as
it is being cut and is then transferred
to a cold adhesive-coated slide.
The adhesive on the slide is polymerized into a plastic layer, securely anchoring the still frozen section to the slide. The section on the slide is now ready for fixation and/or staining.
What are the CryoJane’s™ Special Features?
- Thin sections help clarify structural relationships and reveal morphologic detail.
- Flat two micron sections are excellent for fast immuno-stains, in-situ hybridization, IS-PCR, laser capture micro-dissection (LCM), tissue microarrays, and other molecular diagnostic protocols.
- The CryoJane™ method assures that tissue sections can be maintained un-thawed EVEN AFTER MOUNTING. Therefore, sections can be freezedried in the cryostat in about ten minutes or freeze-substituted in as little as ten seconds and then fixed "anhydrously" to preserve virtually all fine structure present in the snap-frozen block of tissue.Water-soluble enzymes, antigens, and nucleo-proteins are also preserved in-situ, and with appropriate fixation and staining, true localization of enzyme and antigen activity can be visualized.
- The bond between sections and slide is resistant to proteases, alkalis, and acids. No longer will you lose sections after cytochemical digestion steps, or after rigorous protocols such as in-situ hybridization or IS-PCR.
Why are frozen sections generally so inferior to paraffin sections and how does CryoJane™ get around these problems?
- When a cut section is mounted on a room temperature slide, the flow of the melting ice causes water-soluble components of the cell to be displaced by the flow. In the CryoJane Tape-Transfer process, sections are cut, transferred and tightly bonded to the microscope slide without ever being permitted to melt.
- Slow freezing produces large ice-crystals, which damage insoluble structural elements and causes displacement of water-soluble components. In the CryoJane process, the tissue is snap-frozen to minimize ice crystal size.
- When unfixed wet or dry sections are placed in aqueous solutions (even aqueous fixatives) water-soluble substances wash out of the sections.
- We developed an aqueous fixative that maintains the structural
elements in the cell, producing H&E stained slides of high quality.
An alternative method is free-substitution where the ice in the frozen
sections is dissolved (not melted) in a cold (-35ºC) solvent,
yielding"dry" sections, which can then be
fixed appropriately. Free-substitution yields the best morphological results.

Cryo-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.

CureMount™ -
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.

Cryo-Vac-Away
System
The Cryo-Vac-Away adapts to virtually all cryostats. A nozzle at the block-face removes trimming debris as it is generated. The debris is trapped in the Cryo-Vac-Filter and pathogens are captured in the Bacterial-Cryo-Filter inside the cryostat, substantially reducing the biohazard risks associated with infectious material. The cryostat remains clean without unwanted materials.
The Cryo-Vac-Away system includes the following:
Vacuum Blower (1); Foot Switch (2); Swivel Assembly (3); Swivel Assembly Mounting Bracket (4); Collection Nozzle (5); Vacuum Hose (6); Vacuum Hose Adapter Tube (7); Hose Fitting (8); Hose Clamp; Door Channel; 1 Cryo-Vac-Filter; and 1 Bacterial Cryo-Filter.
Notes:
- To fit properly the Cryo-Vac-Away to your Cryostat, please specify your Cryostat model and make.
- If you are planning to purchase a new cryostat, contact EMS. We may able to offer you a Cryostat/CryoJane/Cryo-Vac-Away package.

- Gentle Jane Device
- Heat Extractor; Plastic Thermos
- Stand-Alone Gentle Jane (SAGJ) insulated chamber;
