HOPE^® - Formalin-free fixation technique for molecular pathology and research!

Tissue conservation using the new HOPE^®-technique provides paraffin embedded tissue blocks with native structure of the macro-molecules (protein, DNA, RNA) in the tissue.

A biologically stable buffer system for osmium tetroxide and other EM fixatives. Provides better stability and buffering capacity than traditional veronal acetate buffers.

Methanol, 99.5%, EM Grade.

Acetone can be used for hardening and dehydrating tissues. It can also be used for the extraction of various principles from animal and plant substances.

Useful as a staining agent for electron microscopy of polymers, as well as a fixative for biological samples. Ruthenium tetroxide penetrates tissue very slowly, reacting strongly with proteins, glycogen and monosaccharides.

Hollandes fixative is excellent for large and small gastric tissue, GI biopsies or any tissues that contain large amounts of inflammatory and mucinous cells. This solution is one of the best fixatives for certain kinds of protozoa.

Overnight fixative for the visualization of lymph nodes in radical dissection specimens. Helpful with both breast and colon specimens by turning lymph nodes white.

For Light and Electron Microscopy. This popular methanol-free fixative is a formaldehyde-based material formulated to eliminate the need to select a fixative for tissue based on the type of microscopy to be employed.

Preserve Your Specimens "To Go"

Specially formulated transport medium designed to preserve tissue in a viable state during transport from surgery to grossing by maintaining osmolarity and pH for 24 to 48 hours.

Formaldehyde/Glutaraldehyde fixative commonly used in EM for structural preservation. Pre-measured in ampoules for one-step preparation.

HOPE^® - Formalin-free fixation technique for molecular pathology and research!

Tissue conservation using the new HOPE^®-technique provides paraffin embedded tissue blocks with native structure of the macro-molecules (protein, DNA, RNA) in the tissue.

Used for various research needs. It is ideal for use as a fixative for frozen tissue sections for histology. EM grade quality.

Bouin's fixative is excellent for use in preserving soft and delicate tissue structures. The primary use of Bouin’s is for lymph nodes, prostate biopsies and kidney biopsies, however, it can also be used for decalcifying bones with the addition of formic acid.
