GBL® ROSA-STAIN

2109-Potassium Permanganate Solution

Title Description
REF No 2109
Purpose It is used in microbiology and clinical diagnostics, especially for the detection of acid-resistant bacteria (ARB) such as Mycobacterium tuberculosis. The purpose of this solution is to allow such bacteria to accumulate in the cell walls and to be seen brightly under a fluorescence microscope.
Ingredients Potassium permanganate
Working Principle It is a staining technique used to visualize acid-fast bacilli using fluorescence microscopy. Acid-fast organisms exhibit a reddish yellow fluorescence color. Although the auramine-rodamine stain is not as specific as the Ziehl-Neelsen stain for acid-fast organisms (e.g. Mycobacterium tuberculosis or Nocardia), it gives faster results, so is often used as a screening tool.
Warnings, Precautions, Recommendations
Application 1. Cover with “A-Auramine Rhodamine Solution”. Shake off after 15 minutes.
2. Wash with distilled water.
3. Cover with “B- Acidic Bleaching Solution”. Shake off after 1 minute. You can change the reagent many times during this time.
4. Wash with distilled water.
5. Cover with “C- Potassium Permanganate Solution”. After 3 minutes, shake the preparation to remove the reagent.
6. Wash with running distilled water.
7. Examine under a microscope.
