STUDIES ON NUCLEIC ACID METACHROMASY II. Metachromatic and Orthochromatic Staining by Toluidine Blue of Nucleic Acids in Tissue Sections
Acrolcin-fixed, polyester wax-cmbcddcd tissue sections showed excellent preservation of light microscopic architecture and, when stained with toluidinc blue, intense color contrast between DNA, which stained orthochromatically, and RNA, which stained metachromatically. This method has practical value for differentiating DNA from RNA in the same section. The color c~)ntrast was impaired by subst...

متن کاملSpectroscopic Studies on the Interaction of Toludine Blue Dye with Sodium Alginate Polyelectrolyte
The interaction of Toluidine blue with Sodium Alginate has been investigated by spectrophotometric method. The polymer induces metachromasy in the dye as evidenced from the considerable blue shift in the absorption maxima of the dye. The interaction constant and thermodynamic parameters of polymer-dye interaction have been determined. The effect of alcohols on the reversal of metachromasy has b...
