Then the slide is kept undisturbed for 5 minutes and allows it to cool. Then the smear is decolorized with decolorizing agent (3% HCL in 95% alcohol) but the acid fast cells are resistant due to the presence of large amount of lipoidal material in their cell wall which prevents the penetration of decolorizing solution. second-order differential equation.
