Application

Basic fuchsin is utilized for various applications:
  • Acid-fast staining
  • Periodic Acid-Schiff
  • Feulgen stain for DNA
  • ENDO culture medium
  • Leifson′s method for bacterial flagella

Biochem/physiol Actions

Basic fuchsin displays anesthetic, bactericidal (gram-positive), and fungicidal properties.
