WebTable 3 lists some of the cytochemical stains used in differentiating lineages (there are additional stains not listed here). Table 3 . Cytochemical Tests Used in Differentiating Myeloid Cells from Lymphocytic Cells WebPeriodic acid–Schiff stain. Periodic acid–Schiff ( PAS) is a staining method used to detect polysaccharides such as glycogen, and mucosubstances such as glycoproteins, glycolipids and mucins in tissues. The reaction of periodic acid oxidizes the vicinal diols in these sugars, usually breaking up the bond between two adjacent carbons not ...
