MEDIC, AFB (Hot Method) Ziehl Neelsen, 250 Test

The MEDIC AFB modified staining kit is used for the microscopic analysis of mycobacteria (AFB) by hot staining. The MEDIC AFB modified staining kit is based on the classical Ziehl-Neelsen method. Once stained, the acid fast mycobacteria keep their colouring even after treatment with strong decolorizing solutions as HCl-ethanol. They remain stained red after counterstaining, whereas the microorganisms susceptible to acid take on the color of the counterstain. The staining kit consists of 500 ml carbol-fuchsin solution and 500 ml of the counterstain methylene blue solution, as well as two 500 ml bottles of decolorization solution, hydrochloric acid in ethanol. The kit is sufficient for staining up to 250 slides.
