  • Acid Phosphatase
  • Nonspecific Esterase

  • Oil Red O
  • Myophosphorylase
  • Cytochrome C Oxidase
  • SDH

Further special stains and immunohistochemical stains are available as indicated on a per case basis. Additional muscle tissue is routinely fixed for electron microscopy studies. Extra frozen muscle tissue is also archived for future analysis.
