ABSTRACT:
A process for preserving cellular structures includes the steps of pre-treating the structures with an aqueous polymeric water solution, drying the structures and then post-treating the structures with an organic solvent, non-water-base solution. Once the structure has been treated with the pre-treatment solution, the specimen is allowed to sit for a predetermined period of time in order for the active ingredients of the solution to penetrate the surface area of the specimen. The specimen is then preferably freeze-dried. The solution may also be applied to the cellular material by drawing it systemically through the material.
