words only definitions & notes
  1. counterstain
    a stain of contrasting color that is used when the principal stain does not show the structure clearly
    A suitable basic stain is often used as a counterstain.
    [edit]
    Uses
    PAS staining is mainly used for staining structures containing a high proportion of carbohydrate macromolecules (glycogen, glycoprotein, proteoglycans), typically found in eg. connective tissues, mucus, and basal laminae.
  2. glycoprotein
    a conjugated protein having a carbohydrate component
    A suitable basic stain is often used as a counterstain.
    [edit]
    Uses
    PAS staining is mainly used for staining structures containing a high proportion of carbohydrate macromolecules (glycogen, glycoprotein, proteoglycans), typically found in eg. connective tissues, mucus, and basal laminae.
  3. glycogen
    one form in which body fuel is stored
    This method is primarily used to identify glycogen in tissues.
  4. macromolecule
    any very large complex molecule
    A suitable basic stain is often used as a counterstain.
    [edit]
    Uses
    PAS staining is mainly used for staining structures containing a high proportion of carbohydrate macromolecules (glycogen, glycoprotein, proteoglycans), typically found in eg. connective tissues, mucus, and basal laminae.
  5. macrophage
    a large phagocyte
    However, it has uses beyond this, such as being indicative of certain forms of cancer, such as Paget's disease, or in staining macrophages in Whipple's disease.
  6. aldehyde
    any of a class of highly reactive chemical compounds
    The reaction of periodic acid selectively oxidizes the glucose residues, creates aldehydes that react with the Schiff reagent and creates a purple-magenta color.
  7. histology
    the study of the microscopic structure of tissues
    Periodic acid-Schiff (PAS) is a staining method used in histology and pathology.
  8. oxidize
    enter into a combination with oxygen
    The reaction of periodic acid selectively oxidizes the glucose residues, creates aldehydes that react with the Schiff reagent and creates a purple-magenta color.
  9. lamina
    a thin plate or layer (especially of bone or mineral)
    A suitable basic stain is often used as a counterstain.
    [edit]
    Uses
    PAS staining is mainly used for staining structures containing a high proportion of carbohydrate macromolecules (glycogen, glycoprotein, proteoglycans), typically found in eg. connective tissues, mucus, and basal laminae.
  10. connective tissue
    tissue of mesodermal origin consisting of e.g. collagen fibroblasts and fatty cells; supports organs and fills spaces between them and forms tendons and ligaments
    A suitable basic stain is often used as a counterstain.
    [edit]
    Uses
    PAS staining is mainly used for staining structures containing a high proportion of carbohydrate macromolecules (glycogen, glycoprotein, proteoglycans), typically found in eg. connective tissues, mucus, and basal laminae.
  11. mucus
    protective secretion of membranes lining internal organs
    A suitable basic stain is often used as a counterstain.
    [edit]
    Uses
    PAS staining is mainly used for staining structures containing a high proportion of carbohydrate macromolecules (glycogen, glycoprotein, proteoglycans), typically found in eg. connective tissues, mucus, and basal laminae.
  12. carbohydrate
    an essential component of living cells and source of energy
    A suitable basic stain is often used as a counterstain.
    [edit]
    Uses
    PAS staining is mainly used for staining structures containing a high proportion of carbohydrate macromolecules (glycogen, glycoprotein, proteoglycans), typically found in eg. connective tissues, mucus, and basal laminae.
  13. residue
    matter that remains after something has been removed
    The reaction of periodic acid selectively oxidizes the glucose residues, creates aldehydes that react with the Schiff reagent and creates a purple-magenta color.
