    ALCIAN BLUE -PAS PH 2,5 -KIT MARE( L) Alcian dyes belong to cuprophthalocyanine group; they bind polyanions of acid mucopolysaccharides through saline bounds. In this method, a sodium tetraborate solution transforms the dye into Monastral blue pigment, which is insoluble and can therefore be further manipulated without spreading in the tissue (Alcian blue-PAS). Alcian blue reacts with polyanions whose components are sulphuric and carboxylic radicals (phosphate radicals of nucleic acids do not react). As result, acid mucins only are stained. Specificity (see kit ALCIAN BLUE pH 2,5 - pH 1) - pH 1 Alcian blue ionizes strongly sulphured mucins only. - pH 2,5 Alcian blue ionizes most acid mucins. Method Bring section to distilled water. Put on the section 10 drops of reagent A: leave to act 30 minutes. Drain the slide without washing and put on the section 10 drops of reagent B : leave to act 10 minutes. Wash in distilled water. Put on the section 10 drops of reagent C: leave to act 5 minutes. Wash in distilled water. Dehydrate through ascending alcohols, clear in xylene and mount. Results Acid mucopolysaccharides Nuclei turquoise blue red Reagents Alcian Blue pH 2,5 according to Mowry Sodium tetraborate solution Carmalum according to Mayer 30 ml 30 ml 30 ml
