We currently provide the following special stains:

  • Masson's Trichrome: To demonstrate the differentiation between collagen and smooth muscle in tumors and identify increases in collagenous tissue in diseases.
  • Oil Red O: To demonstrate neutral lipids in frozen tissue section; can only be performed on frozen tissue sections.
  • PAS: A stain to detect polysaccharides, neutral mucosubstances & basement membranes.
  • Picrosirius Red: To visualize collagen I and III fibers in addition to muscle in tissue sections. The PSR stain may be viewed using standard light microscopy or polarized light resulting in birefringence of the collagen fibers to distinguish between type I and type III.
