One can also detect some solitary impregnated neurons. These regions of a neuron are characterized by numerous, short cytoplasmic extensions and. As the fast impregnation methods have the disadvantage of frequent color fade, the buffer composition is preferred among other possible combinations while developing staining due to the long period of stain stability (at least 4 years). 100x, oc. Combining classical silver staining methods and immunohistochemistry together provides an opportunity for the quantitative assessment of tissue sections (Ahmad et al., 2019; Preziosa et al., 2019).

Nevertheless, the methods compiling Nissl staining with immunohistochemistry are still able to supply new data, especially in neurochemistry (Mansour et al., 2019). Rech. which cells are the macrophages of the CNS? It seems that the GFAP method does not reveal a large number of astrocytes (Walz and Lang, 1998), although in the comparative analysis of astrocyte numbers (Figure 3C), we have found it to be almost equal to our staining technique. Therefore, we conclude that protein synthesis occurring in the neurons during their functioning might contribute to the silver reduction. doi: 10.1016/j.heliyon.2019.e03047, PubMed Abstract | CrossRef Full Text | Google Scholar.

Applying a new hybrid staining approach for the assessment of the number and size of neurons and glial cells in the architectonics of the cortex and striatum (Figure 2A), a large number of transversely oriented nerve fibers in the striatum are observed, along with dispersed focal neurons between them, which are stained predominantly with cresyl violet (see Figures 2B,C). The astrocytes of gray matter are difficult to observe with traditional methods, and IHC is also a tricky method because dilution of the primary antibody to GFAP needs careful adjustment.
