It is suggested a new method of brain tissue staining which contrasts cell parts like nucleus, cytoplasm, chromatin ultrastructure and the border of neuron cytoplasm, indistinguished by other methods. Equally with nervous tissue connective tissue is stained well also, blood vessels in particular. Macrophages become metachromatic. The proposed formular is universal and it is suitable for almost all objects of the study in the light microscope: paraffin, cryotomic, vibratomic and semithin sections.
