Application

Certified for use with the Gram stain for bacteria, Flemming triple stain with iodine for chromosomes, Lieb′s amyloid stain and Newton′s crystal violet-iodine technique for chromatin and nucleoli.
Crystal violet is used as an active component, primary stain, of Gram stain for differentiation of Gram-negative versus Gram-positive bacteria.
It has been used to check cell viability.[1] It has also been used for the staining of cells to study cell migration and invasion.

Biochem/physiol Actions

Crystal violet can be used for DNA visualization in agarose gels. The dye is used only in the presence of high concentrations of DNA. Crystal violet is also used for the staining of bacteria in gram staining technique. It is also used for the staining of plant chromosomes. Crystal Violet also helps in colorimetric measurement of cell viability.

Questions

1–3 of 3 Questions  

  1. Can crystal violet or Giemsa be used to stain cells in a saliva/PBS suspension for the purpose of counting neutrophils/mL? What would be the best staining method for this purpose?

    1 answer

    1. Acridine orange is theoretically intended to stain viable cells, and if low intensity is observed, particularly when using a light microscope, it is likely true. However, for visualizing viable cells stained with acridine orange, a fluorescent microscope is routinely used. For simple neutrophil counting in saliva, acridine orange may not be the best choice due to cost considerations.

      While Giemsa solutions can be used, staining can be challenging, and often there are no published procedures for using Wright, Wright Giemsa, or Giemsa solution for counting neutrophils under a hemacytometer. The recommended product for this purpose is Crystal Violet or Turks/Tuerks solution, a simple solution of crystal violet dissolved in water. Acetic acid is sometimes added to the Turks solution to lyse red blood cells, but if the saliva is not bloody, adding acetic acid is unnecessary.

  2. What is the allowed limit of Crystal Violet before it is considered toxic, carcinogenic, or hazardous?

    1 answer

    1. The most serious hazard listed in the Safety Data Sheet (SDS) is Serious Eye Damage, along with short-term and long-term aquatic hazards. There is also a Category 2 hazard as a carcinogen. However, the risk can be reduced by purchasing prepared solutions instead of preparing them from powder to minimize the risk of inhaling the powder. There are no known safe exposure limits for Crystal Violet. The use of appropriate engineering controls, personal protective equipment, and body protection is recommended.

      Helpful?

  3. Can this be dissolved in ethanol or methanol 

    1 answer

    1. While Crystal Violet solutions used for staining often include ethanol or methanol, this product has not been tested for the direct solubility in either alcohol. This compound is readily soluble in water.
