Bacterial Smears Are Fixed before Staining to? Answer It is important to heat fix the bacterial smear before staining so as to‚ kill the bacteria‚ firmly adhere the smear on to the microscopic slide to prevent washing off during staining‚ and to allow the sample to readily take up the stain. Reference: www2.hendrix.edu What is the purpose of heat- fixing the smear? It helps the cells adhere to the slide so that they can be stained.
