coucouuu!

 

alors dans mon cours, j'ai pas spécifiquement les protéoglycanes mais la substance fondamentale du TC est métachromatique, colorée par de bleu de toluidine et PAS+ --> rose fuchsia. La substance fondamentale n'est pas colorée par les colorants habituels. 

 

Mais en soit oui par association, les protéoglycanes sont métachromatiques car le colorant se fixe aux charges négatives.
