Alcian Blue/PAS Stain Kit is a modification of the original Mowry procedure (1,4). Stains mucins - acidic mucosubstances stained blue, nuclei pink to red and cytoplasm pale pink (for visualization of strongly sulfated mucosubstances)
The tissue parts that specifically stain by this dye become blue to bluish-green after staining and are called "Alcianophilic" (akin to "eosinophilic" or "sudanophilic"). The blue color is due to the presence of copper in the molecule. Wash slides in 1X PBS, 2 times for 5 minutes each 2.

The different pH values of the stain liquid can be used to distinguish the mucous substance. Glycosaminoglycans have a high solubility in water, and are easily lost from the tissue during processing, even if non-aqueous fixatives have been used. Alcian Blue is normally prepared at an acidic pH of 2.5.
Therefore, in order to equalize the temperature of the solution, the slides are dipped up and down. (1965) The pH of the alcian blue staining solution is a critical factor in the staining procedure and has a direct effect on the category of mucins that can be demonstrated with the The chemical and histochemical properties of Alcian Blue. The Cresyl Echt Violet, also known as CEV, stain is used to highlight nissl substances and nuclei. Acid mucopolysaccharide (glycosaminoglycan) has been demostrated at the epithelialmesenchymal interface of mouse embryo submandibular glands by (a) specific FIXATIVE: 10% formalin or Hollande's fixative.
