GENERAL DESCRIPTION & APPLICATIONS
Fuchsin is any of several red to purple dyes consisting of the salts (hydrochloride or acetate) of rosaniline and pararosaniline. The chemical structural body is triaminotriphenylmethane. It posses a brilliant green sheen crystals which produce red solution when dissolved. The solution is employed in coloring textiles and leather. It dyes animal and vegetable in nature. It is also used in the commercial preparation of other dyes. Basic fuchsin is used to stain collagen, muscle, or mitochondria. Mitochondria are visible when they are stained by a fluorescent dye. But nucleus and cell membrane are not visible. In aqueous solution with alcohol, fuchsin stains gram-positive and gram-negative bacteria reddish colors. Counterstain of blue-green background to the surrounding tissue is malachite green. Fuchsin is an useful stain for certain slow-growing or fastidious bacteria (Gimenez technique).
  • Acid Fuchsin (acid magenta): a various mixture of sulfonated fuchsins. There are four of these compounds which have three sulfonic groups each. It is used in Andrade's indicator and in various complex stains to demonstrate collagen fibres red and in smooth muscle in contrast to collagen. 
  • Basic Fuchsin (basic magenta): yellow to green powder; soluble in water and alcohol; a mixture of fuchsins and magenta II; dark green powder; used for staining the tubercle bacillus, for distinguishing between coli and aerogenes bact, as an antifungal agent in Castellani's paint, as a germicide, and as a histologic stain, pH indicator.
  • Methyl Violet (crystal violet; gentian violet) : a derivative of pararosaniline; dark green powder; used as an antiallergen and bactericide, acid-base indicator and for the Gram stain; the Flemming triple stain with iodine; and Newton's crystal violet-iodine technique, and in dyeing textile.
