It also helps us to differentiate the bacterial cells . Of 1,000 women who do get screened, 2 could die from cervical cancer. Chemical stains, or chemical stains used in combination with antibodies, tracking proteins that bind to only one type of protein, are applied to thinly sliced tissue. The dark toned background provides contrast to aid in visualizing the bacteria. Minimum cycle times for steam sterilization cycles; Table 8. Basic stains with a positively charge chromogen are preferred because bacterial nucleic acid and certain cell wall components carry a negative charge that strongly attract and binds to the cationic chromogen.
