Auramine O

Fluo-RAL Auramin is used for the detection of mycobacteria, also called AFB (Acid-Alcohol-FastBacilli), through a fluorescence staining technique according to Degommier. Fluo-RAL Auramine colours mycobacteria fluorescent green-yellow.


Used in Fluo-RAL Kit Ref 359000


Kit Fluo-RAL offers a rapid method for the identification of mycobacteria or Acid Fast Bacilli (AFB). The penetration by the discolouring agent of the highly specific structure of the wall is hardly possible.


This property enables the AFB to retain the fluorescent yellow-green colour of the auramine after discolouration with acid and alcohol. The other non-acid-alcohol-resistant bacteria and cell elements are counter-stained red thanks to Thiazine Red.
