Actively involved in the fight against tuberculosis worldwide, RAL Diagnostics markets a wide range of dyes and staining kits for the detection of mycobacteria.
This range includes products for conventional microscopy (Ziehl-Neelsen, Cold ZN, Quick TB) but also for fluorescence microscopy (Fluo RAL Kit).
In a majority of laboratories around the world using fluorescence microscopy, auramine staining with a dark background is still the standard reference. Meanwhile , studies show that a Thiazine Red or Methylene Blue background is more comfortable to read. RAL Diagnostics already markets the Fluo RAL kit with Thiazine Red counterstain.
Kit Fluo RAL Methylene Blue
In order to meet the needs of a majority of users, a new kit has been added to our offer: the Fluo RAL Methylene Blue Kit.
Unlike Potassium Permanganate, which acts as a saturation agent by reducing contrast, counterstaining with methylene blue gives a true background. It allows the reading of information relating to the sample and obtaining in certain cases, better bacilloscopy.
“less experienced users found it easier to focus and less tiring to read the stains with coloured backgrounds (Auramine/Methylene Blue and Auramine/Thiazine Red).” FIND report for WHO, 17 Août 2009.
