The most common and renowned method used for detecting tuberculosis bacteria is staining according to Ziehl-Neelsen. This method uses Carbol Fuchsin as the main dye, acid alcohol as decolourisation medium and Methylene Blue solution as a contrasting dye. BioGnost’s TB-Stain Hot kit contains TB Carbol Fuchsin reagent, two packages of TB Decolorizer and Methylene Blue Loeffler reagent.
TB-Stain Hot Kit

4 x 100ml bottles.
Using kit for 100 tests
Cover the samples completely with the TB Carbol Fuchsin reagent. Carefully heat the glass slide containing the sample
Rinse with tap water until the dye destains.
Cover the sample using using TB Decolorizer and let it set for 15-30 seconds (depending on the sample thickness).
Rinse with tap water.
Stain the sample using BioGnost's Methylene Blue Loeffler reagent.
Rinse with tap water thoroughly.
Dry the section.
Microbiology staining procedures are not standardized and they depend on standard operating procedures of individual laboratories and the
