ABSTRACT

Classical (Feulgen, basophilia and acidophilia reactions and optical anisotropy) and recently developed (critical electrolyte concentration - usual and variant techniques -, tests for apoptosis and AgNOR image analysis) tests for the cytochemistry of DNA, RNA and nuclear proteins are briefly considered in the context of in vitro and in situ research situations.

Keywords: Cytochemistry; DNA; RNA; nuclear proteins.
