[New fixative for the biological material]
Abstract:
New non-toxic fixative for biological material is patented, that is based on aqueous solutions solutions of bivalent copper cations. Optimal molarity of fixative solution (0.2 M) was established experimentally. The method proposed is selective in demonstration of tissue structures using Bielschowsky-Gros impregnation of material by silver nitrate.

Fixation and Sectioning
The simplest type of preparation is the wet mount, in which the specimen is placed in a drop of liquid on the slide. A liquid specimen can be directly deposited on the slide using a dropper. Solid specimens, such as skin scraping, can be placed on the slide before adding a drop of liquid to prepare the wet mount. Sometimes the liquid is simply water, but stains are often added...
