The PAS (periodic acid-Schiff) staining kit - for detection of aldehyde and mucosubstances, is one of the most widely used chemical methods in histology and is specific in staining non-substituted polysaccharides, neutral mucopolysaccharides, muco- and glycoproteins, as well as glycol- and phospholipids. The PAS staining kit contains ready-to-use Schiff′s reagent and periodic acid solution for the staining of approx. 2500-3000 slides. The combination of PAS staining with Alcian blue allows the additional identification of acidic mucosubstances (glycosaminoglycans).
