Tissue Embedding Media

Leica Biosystems Leica Paraplast X-tra (8-1kg)

Paraplast Xtra is recommended for lower temperature infiltration which aids in the prevention of tissue distortion. It is composed of a unique blend of low molecular weight polymers and highly purified paraffins for compression resistance and ribbon continuity. Low viscosity permits complete infiltration of dense tissue.

Electron Microscopy Sciences Cryo Gel, 4.3oz/Dispenser 4.3 OZ

Crogenic gel 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.

To use, simply dispense gel on a room temperature block-holder. Use a cold heat extractor to form a base layer. Dispense additional gel. Place the tissue on top of the gel. Use a cold heat extractor to freeze tissue and form a block.
