Leica Alcian Blue and PAS Special Stain Kit
Combines the components of the Alcian Blue and Periodic Acid Schiff (PAS) stain kits.
Alcian Blue is normally prepared at an acidic pH of 2.5 and is used to identify acid mucopolysaccharides and acetic mucins.
Excessive amounts of non-sulfated acidic mucosubstances are seen in mesotheliomas, certain amounts occur normally in blood vessel walls but increase in early lesions of atherosclerosis.
PAS staining is mainly used for staining structures containing a high proportion of carbohydrates such as glycogen, glycoproteins, proteoglycans typically found in connective tissues, mucus and basement membranes.
Often used to stain kidney biopsies, liver biopsies, certain glycogen storage diseases in striated muscles and suspected fungal infections.
